1 ) A jet fighter flying at 300 m/s (just below the speed of sound) makes a turn of radius 2.75 km. (a)What is its centripetal acceleration ? (b) Suppose the pilot makes an emergency turn to avoid an approaching missile, subjecting himself to a centripetal acceleration of 10 gs ( = 10x9.8 m/s²), while flying at 580 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.)

1 ) A jet fighter flying at 300 m/s (just below the speed of sound) makes a turn of radius 2.75 km.
(a)What is its centripetal acceleration ?
(b) Suppose the pilot makes an emergency turn to avoid an approaching missile, subjecting
himself to a centripetal acceleration of 10 gs ( = 10x9.8 m/s2), while flying at 580 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
