Two Occupy Wall Street protestors are going for a joy ride in a BMW stolen from a corporate executive. Traveling north on the highway at 40 m/s, they meet a police car traveling south at 20 m/s. The police car can both decelerate and accelerate at 5 m/s² but has to slow to 4 m/s before making a "cop turn" which involves an instantaneous change in direction (but not speed). How long, measured from the time they first met, will it take before the police car can catch up with the protestors and give them a thorough pepper spray down? Answer in seconds.
