A motorist travels at a constant speed of 39.0 m/s through a school zone; exceeding the posted speed limit. A policeman stopped at the side of the road gives chase. 7.0 s after the speeding car passes, the police cruiser begins to accelerate at a constant rate of 3.5 m/s?. How much time elapses between the moment the speeder passes the policeman and the policeman catches the speeder?
