Q. An automobile and train move together along parallel paths at 25.6 m/s.

The automobile afterwards undergoes a uniform acceleration of -4 m/s2 because of a red light and comes to rest. It remains at rest for 54.6s and next accelerates back to a speed of 25.6m/s at a rate of 2.85m/s2.

How far behind the train is the automobile when it reaches the speed of 25.6 m/s, assume that the train speed has remained at 25.60m/s?
