The height of ball in first jump h1=e2h The height of ball in second jump h2=e2h1 =e4h0

Q. A ball is released from height $h$ on the ground level. If the coefficient of restitution is $e$ , then what height will after $2$ times jump from ground?

$e h /2$

$2 e h$

$e h$

$e^{4} h$

The height of ball in first jump
$h_{1} = e^{2} h$
The height of ball in second jump
$h_{2} = e^{2} h_{1}$
$= e^{4} h_{0}$

eh/2

2eh

eh

e4h
