The officer immediately begins pursuit at a constant acceleration of 11.8 km/h/s (note the mixed units), just as the speeder passes the officer.
(a) How much time will it take for the police officer to catch up to the speeder, assuming that the Porsche maintains a constant speed?
(b) How fast will the police officer be traveling at this time?

Two cars, a Porsche and a Honda, are traveling in the same direction, although the Porsche is 184 m behind the Honda. The speed of the Porsche is 23.9 m/s and the speed of the Honda is 17.9 m/s. How much time does it take for the Porsche to catch the Honda? [Hint: What must be true about the displacements of the two cars when they meet?]
