An automobile and train move together along parallel paths at 18.4 m/s.
The automobile then undergoes a uniform acceleration of -4 m/s^2 because of a red light and comes to rest. It remains at rest for 27.7s, then accelerates back to a speed of 18.4 m/s at a rate of 2.45 m/s^2.
How far behind the train is the automobile when it reaches the speed of 18.4 m/s, assuming that the train speed has remained at 18.4 m/s? Answers in units of m.
