t (s) v (m s−1) 7 0 V 16 8 5 3 0 The velocity of a particle moving in a straight line is v m s−1 at time t seconds after leaving a fixed point O. The diagram shows a velocity-time graph which models the motion of the particle from t = 0 to t = 16. The graph consists of five straight line segments. The acceleration of the particle from t = 0 to t = 3 is 3 m s−2. The velocity of the particle at t = 5 is 7 m s−1 and it comes to instantaneous rest at t = 8. The particle then comes to rest again at t = 16. The minimum velocity of the particle is V m s−1.
