Heya....!!
Suppose the velocities of the ball are v1 and v2
Collision is head on , so
v2-v1 = e(u1-u2)
➡ v2-v1 = eu ....... ( i )
By the Law of Conservation of momentum
mu+m×0 = mv1+mv2
OR
v1+v2= u.......... ( ii )
v2 = u/2(1-e)....... (iii)
From equations
➡➡ v1/v2 = 1-e/1+e
This is the required ratio of velocities .
HOPE IT HELPS U
