A train starts from rest and accelerates uniformly at 0.6 m s−2^{-2}−2 for 40 s. It then moves at constant velocity before decelerating uniformly at 0.4 m s−2^{-2}−2 to rest. The total distance travelled is 4 km.
Sketch a velocity-time graph for the complete journey, showing the maximum velocity and the duration of the deceleration.
Find the total time taken for the journey.
