Atrain's velocity is slowly decreasing as it approaches a station. about 1 km before it reaches the station, several stowaways jump off the train. what happens to the amount of acceleration if the force remains constant? assume the train is traveling in the positive direction.

Ablue car pulls away from a red stop-light just after it has turned green with a constant acceleration of 0.5 m/s 2 . a green car arrives at the position of the stop-light 6.5 s after the light had turned green. if t = 0 when the light turns green, at what time does the green car catch the blue car if the green car maintains the slowest constant speed necessary to catch up to the blue car? answer in units of s.
