Question 113

A train starts from rest at station A and accelerates uniformly at 0.6 m s-2 for 40 seconds. It then moves at constant velocity before decelerating uniformly at 0.4 m s-2 until it comes to rest at station B. The distance between the stations is 4 km.

a.

Sketch a velocity-time graph for the motion of the train. Mark on the graph the velocity reached after 40 seconds and the duration of the deceleration.

[3]
b.

Determine the total time taken for the journey.
