A bullet of mass 100 g and velocity 25 m/s collides with a thin rod of mass M = 0.9 kg and length L = 45 cm, embedded in it 35 cm below its upper end. The rod can freely rotate around of an axis perpendicular to the plane of the paper, passing through O. 1. Determine the angular velocity of the rod-bullet system immediately after the crash. 2. Calculate the maximum angular displacement of the rod-bullet system. 35 cm
