A ball of mass m moving with velocity v collides head-on which the second ball of mass m at rest. I the coefficient of restitution is e and velocity of first ball after collision is `v_(1)` and velocity of second ball after collision is `v_(2)` thenA. `v_(1)=((1-e)u)/(2),v_(2)=((1+e)u)/(2)`B. `v_(1)=((1+e)u)/(2),v_(2)=((1-e)u)/(2)`C. `v_(1)=u/2,v_(2)=-u/2`D. `v_(1)=(1+e)u,v_(2)=(1-e)u` |
