A train moves along a straight horizontal track between two stations, A and B. The train starts from rest and moves with acceleration of 1.2 m s-2 for 30 seconds. The train then moves at a constant speed before decelerating at a rate of 0.9 m s-2 until it reaches B.
The total distance between the two stations is 6 km.
sketch a velocity-time graph for the motion of the train between A and B.
find the total time taken by the train to travel from A to B.
