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

Question

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) 4 m (C) 8 m (D) 16 m

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

Q. 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

2 m

4 m

8 m

16 m

$h_{n} = h e^{2 n} = 32 (\frac{1}{2})^{4}$
$= \frac{32}{16} = 2 m$
(here $n = 2, e = 1/2)$
