A car and train move together along parallel paths at 25 m/s [W]. The car then undergoes a uniform acceleration of 2.5m/s^2 [E] because of a red light and comes to rest. It remains at rest for 45s, then accelerates back to a velocity of 25m/s [W] at a rate of 2.5m/s^2 [W]. How far behind the train is the car when it reaches the velocity of 25m/s [W], assuming that the train's velocity has remained constant?
