A rocket test sled accelerates at a constant rate of 15 m/s2 from rest while moving along a straight track. The rocket engine turns off instantly when the sled reaches a speed 29 m/s. The sled then moves freely (acceleration - 0) for a period of 7 s, after which the brakes are automatically applied giving a constant deceleration of -25 m/s². What is the total time that the sled is moving?
