Chapter 2, problem 2/028 the 235000-lb space-shuttle orbiter touches down at about 231 mi/hr. at 210 mi/hr its drag parachute deploys. at 39 mi/hr, the chute is jettisoned from the orbiter. if the deceleration in feet per second squared during the time that the chute is deployed is -0.00030v2 (speed v in feet per second), determine the corresponding distance s traveled by the orbiter. assume no braking from its wheel brakes.
