t (s) v (m s−1) 70 62 48 8 0 0 12.6 The diagram shows the velocity-time graph for the motion of a bus. The bus starts from rest and accelerates uniformly for 8 seconds until it reaches a speed of 12.6ms−1. The bus maintains this speed for 40 seconds. It then decelerates uniformly in two stages. Between 48 and 62 seconds the bus decelerates at ams−2 and between 62 and 70 seconds it decelerates at 2ams−2 until coming to rest.
