A metal ball falls from a height of 32 metre on a steel plate. If the coefficient of restitution is 0.5, to what height will the ball rise after second bounce

A

2m

B

4m

C

8 m

D

16m

Text Solution

Verified by Experts

The correct Answer is:
A
`h_(n)= h e^(2n) = 32 ((1)/(2))^(4) = (32)/(16) = 2m` (here `n= 2, e= 1//2`)
