A uniform rod of mass M andw:.bd) b /ybyb leib7 qy 4ffre9/t09ovn y aqk3 a2j8vx+ngth L can pivot freely (i.e., we ignore friction) about abvfi+/k0a rjnfqe8o7x ay3 992tqv y 4 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 shown. [Hint: See Fig. 8–21g.]
