an automobile and a train move together along parallel paths at 39.1 m/s. The automobile then undergoes a uniform acceleration of -4 m/s/s because of a red light and comes to rest. it remains at rest for 22.5 seconds, then accelerates back up to a speed of 39.1 m/s at a rate of 2.53 m/s/s. how far behind the train is the automobile when it reaches the speed of 39.1 m/s, assuming that the train speed has remained at 39.1 m/s. answer in units of m.
