[问答题]
A uniform rod of mass Mg.uao 1 jb*g3e and length L can pivot freely (i.e., we ignorptf3mp,/ha) twih c9) e 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) t c3)hpmpafhw /i),9t 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.]
