A body of mass 2 kg is dropped from rest from a height 20 m from the surface of Earth. The body hiys the ground with velocity 10 m/s, then work done `(g=10m//s^(2))`

A body of mass 2 kg is dropped from rest from a height 20 m from the surface of Earth. The body hits the ground with velocity 10 m/s, then work done: (g=10m//s^(2))

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 hits the ground.

A bullet of mass 10 g is fired horizontally 1000 m/s from a rifle situated at a height 50 m above the ground. If the bullet reaches the ground with velocity 500 m/s the work done against air resistance in the trajectory of the bullet in joule is (g = 10 m/s^(-2))

A body of mass 10 kg is dropped to the ground from a height of 10 metres. The work done by the gravitational force is (g=9.8m//sec^(2))
