A rocket test sled accelerates at a constant rate of 25 m/s² from rest while moving along a straight track. The rocket engine turns off instantly when the sled reaches a speed 31 m/s. The sled then moves freely (acceleration = 0) for a period of 5 s, after which the brakes are automatically applied giving a constant deceleration of -15 m/s². What is the total distance that the sled moves?
