A stone is dropped from the edge of a roof, and hits the ground with a velocity of -120 feet per second. How high (in feet) is the roof?

Answers

The Height of the roof is 225 feet .

Calculation :

y = h - gt2/2 = 0;

h = gt2/2;

v(t) = dy/dt = - gt;

t = - v(t)/g;

h = g/2·v2(t)/g2

= v2(t)/(2g)

= 120²ft2/s²/(2·32ft/s²) =

A force of 5.2 N acts on a 19 kg body initially at rest. Compute the work done by the force in the first second.

Answers

The work done by the force of 5.2 N acting on a 19 kg body initially at rest in the first second is 0.70922 J.

In order to compute the work done by the force in the first second when a force of 5.2 N acts on a 19 kg body initially at rest, we need to use the formula for work done, which is as follows:

Work Done (W) = Force (F) × Displacement (d)

Here,

force acting on the body = F = 5.2 N

Initial velocity of the body = u = 0 (as it is initially at rest)

Mass of the body = m = 19 kg

Time taken by the body to move = t = 1 second

Using the formula for force, we have,

Force (F) = mass (m) × acceleration (a)

=> a = F/m

Substituting the values, we get,

a = 5.2/19 = 0.2737 m/s²

Using the formula for displacement, we have,

Displacement (d) = ut + (1/2)at²

Substituting the values, we get,

d = 0 + (1/2) × 0.2737 × (1)² = 0.13685 m

Now, using the formula for work done, we have,

W = F × d

Substituting the values, we get,

W = 5.2 × 0.13685 = 0.70922 Joules

Therefore, the work done by the force in the first second is 0.70922 J.

Canada and United States both have economies

Answers

Answer:

The United States has a much stronger economy than Canada tho due to Canada's icy terrain.

Explanation:

John has a utility function of the following: UL, C) = L ^BC ^(1-ẞ), where L is leisure and C is consumption. If he works, he receives a real wage w. Outside of the labor market, he has nonlabor market income V. And his endowment of time T is normalized to 1. And the price of goods p is also normalized to 1.
(a) Please write down his budget constraint.
(b) Assuming ẞ = 1/2, V = 100, w = 200, what is his optimal supply of labor?
(c) How much total income does he have?
(d) How much consumption will he make?
(e) Now, consider the case where John is subject to a 10% income tax on labor income only. What is his new optimal supply of labor?

Answers

(a) The budget constraint can be written as: C = wL + V, where C is consumption, w is the real wage, L is leisure, and V is non-labor market income.

(b) With ẞ = 1/2, V = 100, and w = 200, John's optimal supply of labor cannot be determined without information about his preferences for leisure and consumption. The utility function only represents his preferences, but we need additional information to determine the specific amount of labor he would choose to supply.

(c) John's total income is the sum of his labor income and non-labor market income: Total income = Labor income + Non-labor income = wL + V. Without knowing the specific value of L, we cannot calculate the total income.

(d) Similarly, without knowing John's preferences for leisure and consumption, we cannot determine the specific level of consumption he would choose.

(e) In the case where John is subject to a 10% income tax on labor income only, his new optimal supply of labor would depend on the tax rate's impact on his preferences and the trade-off between leisure and consumption. Without further information on his preferences and the specific tax structure, we cannot determine the new optimal supply of labor.

Additional information about John's preferences for leisure and consumption, as well as the specific tax structure, is necessary to calculate his optimal labor supply, total income, consumption, and the impact of the income tax on his labor supply.

A 7.72 kg box is sliding to the right at a constant velocity of 12:14. If the box has a force 53.14 applied to the right, what is the magnitude of the force of friction?
Type your answer...

Answers

Well, you didn't tell us what the unit of the 53.14 is.  But whatever it is, the force of friction is the same 53.14 of them.

The only way the box can move with constant velocity is if the forces acting on it all add up to zero. So the force of friction to the left, holding it back, must be exactly equal to the force pushng it forward to the right.

Notice that none of this depends on the mass of the box, or WHAT the constant velocity IS.  None of that information matters, or makes any difference. It's only included in the question to confuse and distract us.

Answers

Answer:

The fact that a double concave lens is thinner across its middle is an indicator that it will diverge rays of light that travel parallel to its principal axis. A double concave lens is a diverging lens.

consider a converging lens whose focal length is 5.97 cm. an object is placed on the axis of the lens at a distance of 12.9 cm from the lens. how far is the object's image from the lens?

Answers

The object's image is formed at a distance of 3.81 cm from the lens.

According to the thin lens formula, 1/f = 1/do + 1/di, where f is the focal length, do is the object distance and di is the image distance. Substituting the given values, we get:

1/5.97 = 1/12.9 + 1/di

Solving for di, we get:

di = 1/((1/5.97) - (1/12.9))

di = 3.81 cm

Therefore, the object's image is formed at a distance of 3.81 cm from the lens. It is a real image since the image distance is positive. The magnification of the image can be found using the formula M = -di/do, where M is the magnification. Substituting the values, we get:

M = -(3.81/12.9)

M = -0.295

This means that the image formed is smaller than the object and inverted. The negative sign indicates that the image is inverted.

Answers

The lowest possible power rating of the car's engine. In this case, the power is found to be 500,000 watts or 500 kW

The lowest possible power rating of the car's engine can be calculated by using the formula: Power = (1/2) * Mass * Velocity^2 / Time.

Power is the rate at which work is done or energy is transferred, and it can be calculated using the formula: Power = Work / Time. In this case, the work done is equivalent to the change in kinetic energy of the car, which can be calculated using the formula: Work = (1/2) * Mass * Velocity^2.

Given:

Mass of the car (m) = 1000 kg

Final velocity (v) = 100 m/s

Time taken (t) = 10 s

Substituting the values into the formula, we get:

Power = (1/2) * Mass * Velocity^2 / Time

= (1/2) * 1000 kg * (100 m/s)^2 / 10 s

= 500,000 W

Therefore, the lowest possible power rating of the car's engine is 500,000 watts, or 500 kW.

By using the formula for power and substituting the given values, we can calculate the lowest possible power rating of the car's engine. In this case, the power is found to be 500,000 watts or 500 kW. This indicates the minimum power required for the car's engine to accelerate the car from 0 to 100 m/s in 10 seconds.

What is the maximum instantaneous power dissipated by a 2.5 −hp pump connected to a 240−Vrms ac power source?
What is the maximum current passing through the pump?

Answers

The maximum current passing through the pump is approximately 11 amperes.

To find the maximum instantaneous power dissipated by a 2.5-hp pump connected to a 240-Vrms AC power source, follow these steps:

1. Convert the horsepower (hp) to watts (W): 1 hp is equal to 746 watts, so 2.5 hp × 746 W/hp = 1865 W.

2. Determine the maximum power: For an AC power source, the maximum power is √2 times the RMS power. So, the maximum power = 1865 W × √2 ≈ 2637.4 W.

The maximum instantaneous power dissipated by the pump is approximately 2637.4 watts.

To find the maximum current passing through the pump:

1. Use the formula: Power (P) = Voltage (V) × Current (I).

2. Rearrange the formula to solve for current: I = P / V.

3. Calculate the maximum current: I = 2637.4 W / 240 V ≈ 11 A.

Answers

"Comets tend to be faster than asteroids, and it is estimated that there are far more large comets than large asteroids." Correct option is B.

As comets typically originate from farther out than asteroids do, they move at faster speeds when they cross Earth's orbit: An asteroid would need to be larger than 10 kilometres in diameter, whereas a comet would only need to be about 7 kilometres in diameter to hit Earth with enough energy to form Chicxulub crater.

Two factors that differentiate a comet from an asteroid are shape of the orbit and chemical composition.

There are asteroids that are spherical, curved, and even have satellites. A comet circles the Sun similarly to an asteroid, but unlike an asteroid, it is made of ice and dust. Therefore, a comet's ice and dust composition begin to vaporise as it approaches the Sun. Consequently, a comet looks fuzzy and/or has a tail when viewed through a telescope.

one end of a 1.0-m long string is fixed, the other end is attached to a 2.0-kg stone. the stone swings in a vertical circle, passing the top point at 4.0 m/s. the tension force of the string (in newtons) at this point is about?

Answers

T = 51.6 N. At this point, the string's tension force (measured in newtons) is about vertical and passes the bottom point.

What is the string's tension?

A rope or rope is frequently pictured as having only one dimension, being massless, and having no cross section. The tension along the string is a constant and is equal to the strength of the forces exerted by the string's ends if there are no bend in the string, as there can be with vibrations or pulleys.

Explanation:

Since we are aware that the bottom location of a horizontal circular motion is where there is the greatest strain;

T − Mg = F-c = Mv²/r

Where F-c is centripetal force

Since T − Mg = Mv²/r

Let's make T the subject;

T = Mg + Mv²/r

Where g is the acceleration caused by gravity, which is 9.8 m/s2, T is the tension of the rope, M is the mass of the stone, v is its speed, and r is its length.

Considering the query,

M = 2Kg

v = 4 m/s

r = 1m

By entering the pertinent values, we may obtain T;

T = M(g + v²/r) = 2(9.8 + 4²/1)

T = 2(9.8 + 16)

T = 51.6N

A child's toy gun is a spring-loaded launcher for small lightweight balls of mass 15.0 g. When it is loaded and ready, the spring is compressed by 5.00 cm. The spring constant is 250 N/m. Assume no air resistance or friction.

A) What is the initial velocity of the ball, as it leaves the gun (the muzzle velocity) if the toy gun is fired horizontally? Give your answer in m/s.

B) If the toy gun is fired straight up, how high will the ball go as measured from the end of the spring gun? Give the distance in meters.

Answers

(A) The initial velocity of the ball as it leaves the gun (muzzle velocity) when fired horizontally is approximately 0.79 m/s. (B) The ball will reach a maximum height of approximately 0.021 meters when the toy gun is fired straight up, measured from the end of the spring gun.

A) To find the initial velocity of the ball as it leaves the gun (muzzle velocity) when fired horizontally, we can use the principle of conservation of mechanical energy.

Given:

Mass of the ball (m) = 15.0 g = 0.015 kg

Spring constant (k) = 250 N/m

Compression of the spring (x) = 5.00 cm = 0.05 m

Step 1: Calculate the potential energy stored in the compressed spring.

Potential energy (PE) = (1/2) × k × x²

PE = (1/2) × 250 N/m × (0.05 m)²

Step 2: Calculate the kinetic energy of the ball when it leaves the gun.

Since no energy is lost due to air resistance or friction, the potential energy stored in the compressed spring will be converted entirely into kinetic energy.

Kinetic energy (KE) = PE

KE = (1/2) × m  ×v², where v is the muzzle velocity

Step 3: Solve for the muzzle velocity (v).

(1/2) × m × v² = (1/2) × 250 N/m × (0.05 m)²

v² = (250 N/m × (0.05 m))² / m

v² = 0.625 m²/s²

v ≈ √(0.625) m/s

v ≈ 0.79 m/s

Therefore, the initial velocity of the ball as it leaves the gun (muzzle velocity) when fired horizontally is approximately 0.79 m/s.

B) If the toy gun is fired straight up, we can use the principle of conservation of mechanical energy to find the maximum height the ball reaches.

Step 1: Calculate the potential energy stored in the compressed spring (same as in part A).

Potential energy (PE) = (1/2) × k × x²

PE = (1/2) × 250 N/m × (0.05 m)²

Step 2: Calculate the maximum height reached by the ball.

At the maximum height, all the potential energy is converted into gravitational potential energy.

Gravitational potential energy (PE gravity) = m × g × h, where h is the maximum height

PE gravity = (1/2) × k × x²

m × g × h = (1/2) × k × x²

h = [(1/2) × k × x²] / (m × g)

Substituting the given values:

h = [(1/2) × 250 N/m × (0.05 m)²] / (0.015 kg × 9.8 m/s²)

h ≈ 0.021 m

Therefore, the ball will reach a maximum height of approximately 0.021 meters when the toy gun is fired straight up, measured from the end of the spring gun.

water in a cylinder of height 10 ft and radius 2 ft is to be pumped out. the density of water is 62.4 lb/ft . find the work required if (a) the tank is full of water and the water is to be pumped over the top of the tank. work

Answers

The work required to pump out a full cylinder of water with a height of 10 ft and radius of 2 ft over the top of the tank is 62,400 ft-lb.

To find the work required, we first need to calculate the volume of the cylinder, which can be done using the formula V = πr²h, where V is the volume, r is the radius, and h is the height.

In this case, V = π(2 ft)²(10 ft) = 40π ft³.
Next, we find the weight of the water in the cylinder by multiplying the volume by the density (62.4 lb/ft³).

The weight of the water is W = (40π ft³)(62.4 lb/ft³) = 2,496π lb.
Finally, we find the work required to pump out the water by multiplying the weight of the water by the height it must be pumped (10 ft).

The work required is: Work = (2,496π lb)(10 ft) = 24,960π ft-lb ≈ 62,400 ft-lb.
