Question

A ball of mass M moving with a constant velocity strikes against a ball of same mass at rest .e is a coefficient of resubstitution then what what will be the ratio of velocity of 2 balls after collision
?

Answer 1

Hey Mate!!!

Since given coefficient of restitution is e
e= v/u.
where v is the speed of separation and u is the speed of approach
v=ue.
Now

When the two objects of same masses collide, they interchange their momentum which means they exchange their velocities.
So the
velocity of ball 1 after collision=0
velocity of ball 2 after collision=ue
RATIO=UE/0==Infinity
