Question: A train starts from rest and accelerates uniformly, until it has traveled 5.4 km and acquired a velocity of 31 m/s the train then moves at a constant velocity of 31 m/s for 400s. The train then decelerates uniformly at 0.065 m/s2 until brought to a halt.
Part A: How far does the train travel in total?
