A 0.005-kg bullet traveling horizontally with a speed of 1.00 x10^3 m/s enters an 18.6-kg door, embedding itself 11.8 cm from the side opposite the hinges as in the figure below. The 1.00-m-wide door is free to swing on its hinges.
(a) Before it hits the door, does the bullet have angular momentum relative to the door's axis of rotation?
1. yes or no?
(b) Is mechanical energy conserved in this collision? Answer without doing a calculation.
