0005 00-kg bullet traveling horizontally with speed MX 10 m/s strikes an 18.0-kg door, embedding itself 10.0 cm from the side opposite the hinges as shown in Figure Pl1.41. The 1.00-m wide door is free to swing on its frictionless hinges. (a) Before it hits the door, loes the bullet have angular momentum relative to the door's axis of rotation? (b) If so, evaluate this angu- lar momentum. If not, explain why there is no angular momentum. (c) Is the mechanical energy of the bullet- door system constant during this collision? Answer without doing a calculation. (d) At what angular speed does the door swing open immediately after the colli- Sion? (e) Calculate the total energy of the bullet-door system and determine whether it is less than or equal to the kinetic energy of the bullet before the collision.
