A uniform rod of mass M andyg nkdwi0:c1 i npjyu/l6 93q0/mwu ,crwpprfwv2, 9m715-b6tphof p - cib5m length L can pivot freely (i.e., we ignore friction) about a hinge attached to a wall, as in Fig. 8–54. The rod is held tw bp2fcor6-pi7-1 b5r pm,9pm v5hfw 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.]
