Question

A ball is dropped from a height 10m.if 40% of its energy is lost on collision with the earth then after collision the ball will rebound to a height of-

Answer 1

At the top of a bounce, or when a ball is dropped, it will only have stored energy from gravity. Gravitational potential energy is given by:

GPE=m∗G∗h

You can see that stored energy is dependent directly on height. This means that, if a ball is dropped from 10m and loses 40% of that energy, then it will lose the same percentage of its height after the bounce.

If it loses 40% of its height, then 60% will be left. 60% of 10m is 6m.
