A 0.00532 kg bullet is travelling at 474 m/s towards a 1.14 kg, 1.00 m wide door. It hits the door at the edge opposite the hinge at an angle of 90.0 degrees to the surface of the door. The bullet gets stuck in the door, and causes it to swing. What is the angular velocity of the door+bullet combined system just after impact?
