During world war 2, there were some cases where the crew fell out of burning aircraft without a parachute and survived the fall. assume that the crew member reached a constant terminal speed of 127.1 km/hr prior to hitting a stack of loose hay. if the crew member can survive an acceleration of 36.0 g, where g is the gravitational constant, and assuming uniform acceleration, how high a stack of hay is required for the crew member to survive the fall?
