QUESTION:

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. $8-54$ . 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. $8-21\ g.]$
