A motorist travelling with a constant speed of 1.5 x 10" m/s passes a school- crossing corner, where the speed limit is 1.0 x 10 m/s. Just as the motorist passes the school-crossing sign, a police officer on a motorcycle stopped there starts in pursuit with a constant acceleration of 3.0 x 10' m/s a. How much time elapses before the officer passes the motorist? b. What is the officer's speed at that time? C. At that time, what distance has each vehicle traveled
