Question 197

A train moves along a straight horizontal track between stations A A\,A and BBB. It starts from rest and accelerates at 0.6 m s-2 for 40 s. It then travels at constant speed before decelerating at 0.4 m s-2 until it reaches BBB. The distance AB AB\,AB is 4 km.

a.

Sketch a velocity-time graph for the journey, showing the maximum speed and the duration of the deceleration.
