Q. A 80 g, 33-{rm cm}-long rod hangs vertically on a frictionless, horizontal axle passing through its center. A 11 g ball of clay traveling horizontally at 2.5 m/s hits and sticks to the very bottom tip of the rod.

To what maximum angle, measured from vertical, does the rod (with the attached ball of clay) rotate?

Q. A 2.69 kg steel ball strikes a massive wall at 11.4 m/s at an angle of α=65.8° with the plane of the wall. It bounces off with the same speed and angle (as seen in the figure below).
