A thin stick of mass 0.5 kg and length L = 0.4 m is attached to the rim of a metal disk of mass M = 5.0 kg and radius R = 0.3 m. The stick is free to rotate around a horizontal axis through its other end (see the following figure).
(a) If the combination is released with the stick horizontal, what is the speed (in m/s) of the center of the disk when the stick is vertical?
(b) What is the acceleration (in m/s2) of the center of the disk at the instant the stick is released? (Enter the magnitude.)
(c) What is the acceleration (in m/s2) of the center of the disk at the instant the stick passes through the vertical?
