A train travels from rest, going from station A to station B which is a distance of 2100 metres. For the first 20 seconds the train accelerates steadily, reaching a speed of 25 m/s . It maintains this speed until the brakes are applied and the train is brought to rest with uniform deceleration over the last 125 metres.
