A train is at rest at a station. The train then moves away from the station and after 20 seconds it's velocity is 15m/s and moves at this velocity for 60 seconds. it's velocity increases to 20m/s over 5 seconds. it moves at a velocity of 20m/s for 120 seconds and then slows down to come to a stop after a further 30 seconds. during which period was the acceleration of the train the highest?
