[问答题]
A uniform rod of mass M and length L can pivot freely (i.ek t 8mpx6f-1ye., we ignore frpr6komzm 5t4-iction) 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 totrk4 5m pm6-zhe force of gravity acts at the center of mass of the rod, as shown. [Hint: See Fig. 8–21g.]
