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

2 m

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 = 2m`(here , n=2, e=1//2)`
