A ball is dropped from a height of 12 m on a horizontal slab. If it rebounds to a height of 8 m , find the coefficient of restitution.

Explanation

The coefficient of restitution is a measure of the elasticity of the collision. It is defined as the ratio of the rebound velocity to the initial velocity. In this case, the initial height is 12 m and the rebound height is 8 m.
