Two balls, A and B, each of mass 1.0 kg, initially travel at the velocities VA = (10î + 20j ) m/s and Vg = (-10î + 5j ) m/s, respectively. Immediately after their collision V = (-3ï + 15j ) m/s. No net external force acts on the two balls. What is the final velocity of ball A? What is the change in the balls' total kinetic energy? (b) 5.
