9.41. Consider a disk of mass mi and radiusr attached to a rod of length L and mass M. The system is suspended from the other end of the rod and allowed to oscillate. Find the time period of the os- cillations. If the disk is mounted in such a way as to be free to spin (mounted on a frictionless bcar- ing), what will be the period of oscillations? 9.42. Suppose a batter lets go of the bat after the ball hits the bat and that the bat starts rotating. For a quarter of a rotation of the bat, describe and sketch the motion of (a) the center of mass, and (b) the center of percussion; that is, plot x(1) and y(1) for both. Neglect the effect of gravit. d ridc L. The plate swings as a compound pendulum with an
