The velocity of a particle at time t s after leaving a fixed point O is vms¯¹. The diagram shows a velocity-time graph which models the motion of the particle. The graph consists of 5 straight line segments. The particle accelerates to a speed of 0.9ms¯¹ in a period of 3s, then travels at constant speed for 6 s, and then comes instantaneously to rest 1 s later. The particle then moves back and returns to rest at O at time T s. [Figure 4.1]
