A 10.0-g bullet traveling horizontally with a speed of 400 m/s strikes a 15.0-kg door, embedding itself 0.50 m from the side opposite the hinges as shown in Figure P11.30. The 1.00-m wide door is free to swing on its frictionless hinges. (1) At what angular speed does the door swing open immediately? (2) Calculate the initial momentum of the bullet–door system.
