[问答题]
A uniform rod of mass M and length y( ;1jmoddt1nL can pivot freely (i.e., 4zom7 d vx/x-qwe 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 t/d74 ovxxqz- mhe 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.]
