A 0.00400 kg bullet traveling horizontally with speed 1.00 x 10 m/s strikes a 16.6 kg door, embedding itself 11.3 cm from the side opposite the hinges as shown in the figure below. The 1.00 m wide door is free to sving on its frictionless hinges. Hinge (a) Before it hits the door, does the bullet have angular momentum relative the door's axis of rotation? O Yes O No (b) If so, evaluate this angular momentum (in kg • m/s). (If not, enter zero.)
