How high above the ground is a 20 kg box if it has 500 joules of gravitational potential energy? 25 m 17.

How do you solve for kinetic energy?

In classical mechanics, kinetic energy (KE) is equal to half of an object’s mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.

What is the potential energy of a statue with a mass of 15 kg resting on a shelf that is 20 m high?

600J
Calculate the potential energy of an object with a mass of 15 kg while sitting on a shelf that is 20 m high. – E=m.g.h E =? h =? gim E=600J .

What is potential energy formula?

Simplified, this formula can be written as: Potential Energy = mgh, where m is the mass, measured in kilograms; g is the acceleration due to gravity (9.8 m/s^2 at the surface of the Earth); and h is the height, measured in meters.

What is the velocity of a 500 kilogram elevator?

Answer the velocity of the elevator is 4ms .

How do you calculate potential energy loss?

The loss of gravitational potential energy from moving downward through a distance h equals the gain in kinetic energy. This can be written in equation form as −ΔPEg = ΔKE. Using the equations for PEg and KE, we can solve for the final speed v, which is the desired quantity.

How do you compute potential energy?

The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.

What is the potential energy of a 3kg ball that is on the ground?

In this example, a 3 kilogram mass, at a height of 5 meters, while acted on by Earth’s gravity would have 147.15 Joules of potential energy, PE = 3kg * 9.81 m/s2 * 5m = 147.15 J.

What is the potential energy if a body of mass 250 kg is at a height of 30 meters?

Answer: 7500 is the answer of this question….
