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.
