Question

Two balls A and B of masses m and 2m respectively are lying on a smooth surface as shown in the
figure. Ball A hits the ball B (which is at rest) with a velocity v = 16 m/s, such that B just reaches the
highest point of inclined plane. (g = 10m/s)
fe is the coefficient of restitution and V, is velocity of the ball A after collision.
