A thin, cylindrical rod script i = 21.0 cm long with a mass m = 1.20 kg has a ball of diameter d = 6.00 cm and mass M = 2.

A thin, cylindrical rod script i = 21.0 cm long with a mass m = 1.20 kg has a ball of diameter d = 6.00 cm and mass M = 2.00 kg attached to one end. The arrangement is originally vertical and stationary, with the ball at the top as shown in the figure below. The combination is free to pivot about the bottom end of the rod after being given a slight nudge.
