The 24-lb space-shuttle orbiter touches down at about 228 mi/hr. at 181 mi/hr its drag parachute deploys. at 36 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 -0.00034v2 (speed v in feet per second), determine the corresponding distance s traveled by the orbiter. assume no braking from its wheel brakes.
