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

8m

D

16 m

Text Solution

Verified by Experts

The correct Answer is:

A

`h _(n) = he ^( 2n) = 32 ((1)/(2)) ^(4) = (32)/(16) = 2 m`
(here `n = 2, e = 1//2).`
