A jeepney and a train are moving together along parallel paths at 30.0 m/s, with the jeepney adjacent to the rear of the train. The jeepney driver sees the traffic light turn red, so he accelerates at -2.50 m/s2, and then let his jeepney come to rest. The jeepney is at rest for 50.0 s, and then accelerates at 2.50 m/s2 to go back to a speed of 30.0 m/s. Assuming that the speed of the train remained constant at 30.0 m/s, how far is the jeepney from the rear of the train when the jeepney reaches a speed of 30.0 m/s?
