A motorcycle is speeding on a straight, level highway at constant speed. At t = 0, the motorcycle passes a police car that is initially at rest. The officer gives chase, but the motorcyclist doesn’t notice and keeps moving at constant speed. The graph below shows v_x(t) for both. 

(a) When are the motorcycle and police car moving at the same speed? 

(b) At t = 16 s, has the police car caught up with the speeder? Explain. 

(c) What is the velocity of the motorcycle with respect to the police car at t = 5 s and t = 10 s?
