A goods train starts from rest at point A and moves along a straight track. The train moves with acceleration a m/s^2 at time t s, given by a=0.1t^2(6-t) for 0<t<6. It then moves at constant velocity for 6<t<156 before decelerating uniformly to stop at point B at t=165. Calculate the distance from A to B.
I have no clue how to solve this.
I used the usual method without integration and got s=1700m. The textbook ans says 1690.
