A uniform rod of masakpspzy gh65tbn 85+.s M and length L can pivot:34knv lmoh*8,h70yieqx)hg r+nu0vl pe(ny 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 fmvyull+n p r gh3eo 87k,:hih0xy)q*n0n4 (evorce of gravity acts at the center of mass of the rod, as shown. [Hint: See Fig. 8–21g.]
