Introduction: Angular momentum
                        
More Details: A 0.006 00-kg
                bullet traveling horizontally with a speed of 1.00 103 m/s enters an 19.1-kg door, imbedding itself 8.20 cm from the side opposite the hinges as in the figure
                below. The 1.00-m wide door is free to swing on its frictionless hinges.
                
                
                
                (a) Before it hits the door, does the bullet have angular momentum relative the door's axis of rotation?
                Yes
                No
                
                
                (b) If so, evaluate this angular momentum. (If not, enter zero.)
                
                __________m^2/s
                
                
                (c) Is mechanical energy of the bullet-door system constant in this collision? Answer without doing a calculation.
                Yes
                No
                
                
                (d) At what angular speed does the door swing open immediately after the collision?
                
                ______________rad/s
                
                
                (e) Calculate the 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.
                KEf =
                
                _________J
                
                KEi =
                
                _________J
            
            
                 
            
            
                 
            
            
                I know that a is yes and c is no, but I'm not sure how to do the others.
