A ball of mass 'm' moving at a speed v makes a head on collision with an identical ball at rest. The kinetic energy of balls after the collision is 3/4th of the origial. If e is the coefficient of restitution, then :

1.	A ball of mass 'm' moving at a speed v makes a head on collision with an identical ball at rest. The kinetic energy of balls after the collision is 3/4th of the origial. If e is the coefficient of restitution, then :
Answer» `v_(1) = (1-(1)/(SQRT(2)))/(2)V` `v_(2) = (1+(1)/(sqrt(2)))/(2)v` `E = (1)/(sqrt(2))` `e = (1)/(2)` Answer :A::B::C
