A bomb of mass 40 kg is dropped from an aeroplane at a height of 1 km above the ground. What is its kinetic energy (i) at the end of 10 s and (ii) on reaching the ground ?

A body of mass 10 kg is dropped from a height of 20 m. (Take g = 10 3/s^2) Its kinetic energy when it is 8 m abgve the ground

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.
