5. A train started from a station and accelerated at 0.5 m s² to reach its top speed of 50 m s¯¹ and
maintained this speed for 90 minutes.
As the train approached the next station the driver applied the brakes uniformly to bring the train to a
stop in a distance of 500 m.
(i) Calculate how long it took the train to reach its top speed.
(ii) Calculate the acceleration experienced by the train when the brakes were applied
