Ball 1 collides directly with another identical ball 2 at rest. Veloci

1.	Ball 1 collides directly with another identical ball 2 at rest. Velocity of second ball becomes two times that of 1 after collison. Find the coefficient of restitution between the two balls?
Answer» Here `m_(1) = m_(2)` and `u_(2) = 0` After collision, `v_(2) = ((1+e)/(2))u` & `v_(1) = ((1-e)/(2))u` Given `v_(2) = 2v_(1) , ((1+e)/(2)) u=2((1-e)/(2))u` `1 +e =2 - 2e , 3e = 1, e = (1)/(3)`.
