A uniform rod of mass M uv:hrp5bekwwl ,0fj5q fl*-;s1 8akmand lengq hrlka3 bn0kzc r264-th L can pivot freely (i.e., we ignore friction) about a hinge attached to a wall, as in Fig. 8–54. 42hrr n-zck63lb0k qa 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 force of gravity acts at the center of mass of the rod, as shown. [Hint: See Fig. 8–21g.]
