Two smooth balls A and B , each of mass m and radius R , have their centres as shown in fig. Ball A , moving along positive x-axis, collides with ball B . Just before the collision, speed of ball 'A' is 4m//s and ball 'B' is stantionary. The collision Coefficient of restitution during the collision is changed to (1)/(2) , keeping all other parameters unchanged. What is the velocity of the ball 'B' after the collision.
