A 30-g bullet is fired with a horizontal velocity of 350 m/s into the 8-kg wooden beam AB. The beam is suspended from a collar of negligible mass that can slide along a horizontal rod. Neglecting friction between the collar and the rod, determine the maximum angle of rotation of the beam during its subsequent motion.
