A uniform rod of mass M and length L can pivot freely (i.e.6jy60q (+icat;n zbdu, kqn9n6sik j6zrq (np(vd;+z60fd(ns 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 forc fzpddk((n666sj n + 0(kszi n;q9vnrqe of gravity acts at the center of mass of the rod, as shown. [Hint: See Fig. 8–21g.]
