[问答题]
A uniform rod of mass M and lengttu*:c;(cghaz3u4ktju 7p jv* h L can pivot freely (i.e., we ignore frimt+z+/t 1 yxrick4 ik8ction) 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 rz+4/t 1+cxi8 tkmrk yiod, 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. 8–21g.]
