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 3.3 kg, is moving upward at 22 m/s and the other ball, of mass 1.9 is moving downward at 13 m/s. How high do the combined two balls of putty rise above the collision point? (Neglect air drag.)

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 3.3 kg, is moving upward at 25 m/s and the other ball, of mass 2.0 kg, is moving downward at 13 m/s. How high do the combined two balls of putty rise above the collision point? (Neglect air drag.) Number Units

Squid rely on jet propulsion when a rapid escape is necessary. A 1.5 kg squid at rest pulls 0.10 kg of water into its mantle, then ejects this water at a remarkable 45 m/s. Right after this ejection, how fast is the squid moving?

(a) A 13.0 g wad of sticky clay is hurled horizontally at a 110 g wooden block initially at rest on a horizontal surface. The clay sticks to the block. After impact, the block slides 7.50 m before coming to rest. If the coefficient of friction between block and surface is 0.650, what was the speed of the clay (in m/s) immediately before impact? _____ m/s (b)What If? Could static friction prevent the block from moving after being struck by the wad of clay if the collision took place in a time interval Δt = 0.100 s? Explain your answer. Yes, a slightly larger coefficient of static friction could reasonably prevent the block from moving. No, the coefficient of static friction that would be required is unrealistically large.
