A ball is dropped from a height of 20 m . If the coefficient of restitution for the collision between ball and floor is 0 . 5 , after hitting the floor, the ball rebounds to a height of ______ m .

Question

TestHub · Accepted Answer

As we know h ' = e 2 h , where h ' = height after the collision, h = height before the collision and e = coefficient of restitution. Therefore, h ' = 0 . 5 2 × 20 m = 5 m
