A completely inelastic collision occurs between two balls of wet putty that move directly toward each other along a vertical axis. Just before the collision, one ball, of mass 3.1 kg, is moving upward at 24 m/s and the other ball, of mass 1.7 kg, is moving downward at 14 m/s. How high do the combined two balls of putty rise above the collision point? (Neglect air drag.)
