a train accelerates uniformly starting from rest at train P to reach a maximum speed of 60kmh-1. It maintains this speed for a time and then decelerates uniformly to stop at a station Q, 27.5km from P. The total time taken from P to Q is 40 minutes. If the magnitude of the acceleration is 2/3. Draw the speed time graph and find: a) the time for which the maximum speed is maintained. b) the deceleration
