Question

Two balls of mass ratio $1:2$ are dropped from the same height.
(i) State the ratio between their velocities when they strike the ground.
(ii) The ratio of the forces acting on them during motion.

Answer 1

$V=\sqrt{2gh}$ does not depend on mass
(i) ratio of velocity $=1:1$ because they are released from same height.
(ii) $mg$ force acts on first, $2mg$ acts on second one
$\therefore$ ratio of force $=1:2$
