Momentum: three balls move in the same straight line. Balls A and B move in the same direction at velocities of 2m/s and 8m/s respectively. Ball AC moves in the opposite direction at 6m/s and collides with ball B, whereafter ball B collides with ball A. the masses of balls A, B and C are 4kg, 12kg and 10kg respectively calculate: the velocity of and direction of ball C after the collision between balls B and C
