15.46: A uniform rod lvr9x -jd2wev/h. h, u of mass M an eon6m* k7iwk)krn5 1yd length L is fixed to rotate about a frictionless pivot located L/3 from one end. The rod is released from rest incrementally away from being perfectly vertical, resulting in the rod rotating clockwise about th o6e7nwy*n5 1kkik) rme pivot. When the rod is horizontal, what is the magnitude of the tangential acceleration of its center of mass?
A. $g/6$
B. $g/2$
C. $4g/3$
D. $2g/3$
E. $g/4$
