Answer:
Explanation:
Given
Initial velocity of first billiard ball 
Initial velocity of second billiard ball 
After collision first ball comes to rest
suppose m is the mass of both the balls
Conserving momentum to get the speed of second ball after collision
Initial momentum 
Final momentum 
where
and
are the speed of first and second ball respectively



thus speed of second ball after collision is equal to speed of first ball before collision
