Question
A ball of mass 
rests on a vertical post of height 
. A bullet of mass 
, travelling with a velocity 
in a horizontal direction, hits the centre of the ball. After the collision, the ball and bullet travel independently. The ball hits the ground at a distance of 
and the bullet at a distance of 
from the foot of the post. The initial velocity 
of the bullet is
The correct answer is:
and 
Applying momentum conservation just before and just after the collision
