Loss of energy =35 % Remaining energy =65 % New energy =65 % of initial energy mghâ²=(65/100)mgh hâ²=(65/100)× 100 hâ²=65 textm

Q. An inelastic ball is dropped from a height $100 m e t er$ . If due to impact it loses $35%$ of its energy the ball will rise to a height of

$35 m$

$65 m$

$100 m$

$135 m$

Loss of energy $= 35%$
Remaining energy $= 65%$
New energy $= 65%$ of initial energy
$m g h^{'} = \frac{65}{100} m g h$
$h^{'} = \frac{65}{100} \times 100$
$h^{'} = 65 m$
