Question

A jet fighter flying at 300 m/s (just below the speed of sound) makes a turn of radius 1.80 km. (a) What is its centripetal acceleration in gs?
g

(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 455 m/s (supersonic). What is the radius 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.)

Explanation / Answer

v=300m/s , r =1.8km=1800m

Part (a):

a =v2/r = 300x300/1800

a =50 m/s2

Accelration in terms of g value is a=50 xg/9.8

a=5.1 g

Part (b) :

a=10g, v =455m/s

r =v2/a = (455x455)/ (10x9.8)

r = 2112.5 m

r =2.1km
