Answer:
(c) Displacement is the difference between the final and initial position of a body. It is a vector quantity and is independent of the path taken. So, for the movement of half of a circle, the displacement is 2r, where r is the radius of the circular path.

At , the driver applies the brakes and the resistive force on the train causes it to decelerate uniformly to rest in a further .
Fig. is an incomplete distance-time graph for this journey.
While the train decelerates to rest, it does work against the resistive force and its kinetic energy decreases.
Using figure, determine the distance moved by the train while it decelerates.
