Question 74

A train accelerates from rest at station A to a velocity of 32 m s−1^{-1}−1. It maintains this velocity for 72 s and then decelerates uniformly to rest at station B. The total journey time is 112 s, and the magnitudes of the acceleration and deceleration are equal.

a.

Find the time taken for the train to accelerate from rest to 32 m s−1^{-1}−1.

[2]
b.

Sketch a velocity-time graph for the motion of the train between A and B.

[2]
c.

Calculate the distance between the two stations.
