A uniform rod of mass Me pj2y(xu g .,,u:wfhg and length L can pivot freely ( ;hi0nqf7 )z8+zu53czp upfsbi.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 force of gravity acts at the center of mass of the rod, as shownp8zu i+ pzb5 zh7fn3scq);0 uf. [Hint: See Fig. 8–21g.]
