19-31. The 10-g bullet having a velocity of 800 m/s is fired into the edge of the 5-kg disk as shown. Determine the angular velocity of the disk just after the bullet becomes embedded into its edge. Also, calculate the angle 0 the disk will swing when it stops. The disk is originally at rest. The rod AB has a mass of 3 kg. 2 m v = 800 m/s %3D 0.4 m
