QUESTION:

A uniform rod of mass  and length  can pivot freely (i.e., we ignore friction) about a hinge attached to a wall, as in Fig. . The rod is held horizontally and then released. At the moment of release, determine (a) the angular acceleration of the rod, and  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. 8-21g.]
