**Centripetal Acceleration in Aviation**

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 g<sub>s</sub> (= 10 x 9.8 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 g<sub>s</sub>.)
