In the figure, block A (mass 1.9 kg) slides into block B (mass 2.3 kg), along a frictionless surface. The directions of velocities before and after the collision are indicated; the corresponding speeds are Vai = 5.6 m/s, vBi = 2.8 m/s, and VBf = 4.8 m/s. What is velocity vaf (including sign, where positive denotes motion to the right)? Number i Units

In the figure, block A (mass 1.9 kg) slides into block B (mass 2.3 kg), along a frictionless surface. The directions of velocities before and after the collision are indicated; the corresponding speeds are VAi = 5.6 m/s, vBi = 2.8 m/s, and VBf = 4.8 m/s. What is velocity vaf (including sign, where positive denotes motion to the right)? %D VAy = ? Number Units

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 3.4 kg, is moving upward at 23 m/s and the other ball, of mass 2.1 kg, is moving downward at 15 m/s. How high do the combined two balls of putty rise above the collision point? (Neglect air drag.) Number Units
