Answer: s= i
Current Attempt in Progress
The 242000-lb space-shuttle orbiter touches down at about 229 mi/hr. The drag chute is deployed at 183 mi/hr, the wheel brakes are
applied at 82 mi/hr until wheelstop, and the drag chute is jettisoned at 29 mi/hr. If the drag chúte results in a deceleration of
-0.000180v² (in feet per second squared when the speed v is in feet per second) and the wheel brakes cause a constant deceleration of
5.5 ft/sec², determine the distance s traveled from 183 mi/hr to wheelstop.
