A driving instructor gives a student a sudden order to stop the car in the shortest possible time.
Fig. 1.1 above shows the speed-time graph of the motion of the car from the moment the order is given.
(a) The order to stop is given at time t = 0 s.
(i) State the speed of the car at t = 0 s.
(ii) Suggest why the car continues to travel at this speed for 0.9 s.
(b) Calculate
(i) the deceleration of the car between t = 0.9 s and t = 4.0 s.
(ii) the total distance travelled by the car from t = 0 s.
(c) Describe and explain a danger to a driver of not wearing a safety belt during a sudden stop.
