t (s) v (m s−1) 50 35 30 5 0 0 U V 12 The diagram shows a velocity-time graph which models the motion of a tractor. The graph consists of four straight line segments. The tractor passes a point O at time t = 0 with speed U m s−1. The tractor accelerates to a speed of V m s−1 over a period of 5 s, and then travels at this speed for a further 25 s. The tractor then accelerates to a speed of 12 m s−1 over a period of 5 s. The tractor then decelerates to rest over a period of 15 s. 2
