help! please write the complete solutions. Thumbs-up willl be given! DYNAMICS OF RIGID BODIES! A subway car leaves station A; it gains speed at the rate of 4ft /s2 for 6 s and then at the rate of 6ft /s2 until it has reached the speed of 48 ft/s. The car maintains the same speed until it approaches station B; brakes are then applied, giving the car a constant deceleration and bringing it to a stop in 6 s. The total running time from A to B is 40s. Determine the distance between stations A and B.
