The diagram shows a velocity-time graph which models the motion of a particle. The graph consists of 3 straight line segments. The velocity of the particle at time ts after passing a fixed point O is vms⁻¹. The particle leaves O with a velocity of 5 ms⁻¹ and accelerates at 0.75 ms⁻² for 20s. The particle then decelerates for the next 30s. At t = 40, the velocity of the particle is zero. After t = 40, the particle starts to travel back to O, coming to rest at O at time Ts.
