A jet fighter flying at 300 m/s (just below the speed of sound) makes a turn of radius 2.55 km.   (a)What is its centripetal acceleration in gs?   (b)Suppose the pilot makes an emergency turn to avoid an approaching missile, subjecting himself to a centripetal acceleration of 10 gs, while flying at 400 m/s (supersonic). What is the radius, in km, of his turn? (This must be short-lived because fighter planes can only briefly endure such large accelerations without serious damage, and the pilot will soon black out at 10 gs.)
