1 A high speed passenger train is travelling at a velocity of 54 m s–1.
The simplified graph shows the variation with time t of the velocity v of the train until it stops.
At t = 0 the driver starts to think about applying the brakes.

(a) Use the graph to determine the acceleration a of the train while the driver applies the brakes.
a = .....
–......................... m s –2 [1]
(b) Use the graph to determine the total stopping distance d of the train from t = 0.
d = ....................................................... m [2]
(c) Suggest why the graph does not show the real motion of the train.
