A uniform rod of mass M and length l can pivot freely
(i.e., we ignore friction) about a hinge attached to a wall,
as in Fig. 8-63. The rod is held horizontally and then
released. At the moment of release, determine (a) the angular
acceleration of the rod, and (b) the linear acceleration
of the tip of the rod. Assume that the force of gravity
acts at the center of mass of the rod, as shown. [Hint: See
Fig. 8–20g.]
