At what height above the ground must a mass of `5 kg` be to have its `PE` equal in value to the `KE` possessed by it when it moves with

An object of mass 40 kg is raised to a height of 5 m above the ground. What is its potential energy? If the object is allowed to fall, find its kinetic energy when it is half way down.

An object of mass 4 kg is raised to height of 5 m above the ground. What is its potential energy ? If the object is allowed to fall, find its kinetic energy when it is half way down.

An object of mass 40 kg is raised to height of 5 m above the ground. What is its potential energy? If the object is allowed to fall, find its kinetic energy when it is half-way down.

An object of mass 40 kg is raised to a height of 5 m above the ground. What is its potential energy ? If the object is allowed to fall, find its kinetic energy when it is half - way down.

An object of mass 40 kg is raised to a height of 5 m above the ground. What is its potential energy ? If the object is allowed to fall, find its kinetic energy when it is half - way down.

A body of mass 10 kg is kept at a height of 5 m. It is allowed to fall and reach the ground. What is the kinetic energy possessed by the body just before hitting the ground? (Take g = 10m//s^(2) ).

A mass of 20 kg is at a height of 8 m above the ground. Then the potential energy possessed by the body is: [Given g = 9.8 ms^(-2) ]

A raindrop of mass 1.00 g falling from a height of 1m hits the ground with a speed of 50 ms^(-1) Calculate (a) the loss of PE of the drop (b) the gain in KE of the drop ( c ) Is the gain in KE equal to loss of PE ? If not why ? Take, g =10 ms^(-2)
