6. Calculate the distance between the stations. For each of the time intervals OA, AB and BC, state the value of the train's acceleration. The train starts from rest at the first station and accelerates uniformly for 360 m, reaching a speed of 36 ms 1. In a model of the motion of the train, at time=0 the train starts from rest at P, and moves with constant acceleration until it reaches its maximum speed of 25 ms The train then travels at this constant speed of 25 ms before finally moving with constant deceleration until it comes to rest at Q. The train then travels at this constant speed before it moves with constant deceleration 0.25 m s-2 until it comes to rest at B. That is no surprise because 3 miles / min = 180 miles/hour which is a bit nuts just coming out of the station. A train is moving along a straight section of the track with a velocity of 180 km/h.
