For a stunt plane flying at a speed of 250 km/h , what is the minimum radius of downward curve a...
Stunt pilots and fighter pilots who fly at high speeds in a downward-curving arc may experience a “red out,” in which blood is forced upward into the flier’s head, potentially swelling or breaking capillaries in the eyes and leading to a reddening of vision and even loss of consciousness. This effect can occur when the non-gravitational part of the centripetal acceleration exceeds 2.5 g’s.For a stunt plane flying at a speed of 250 km/h, what is the minimum radius of...
