Consider a level flight turn of a propellerdriven airplane in which the airplane makes a complete circular turn in 1.6 min. If the plane's speed is 180 m/s, what is the radius of the circle?
1 m
What is the centripetal acceleration of the plane?
2 m/s2

180 m/s * 96s
=17280 m
radius = 17280/2π
=2750.2m
angular velocity
=2π/96s rad./s
=π/48 rad/s
Centripetal acceleration
=rω² m/s²
I get about 11.8 m/s²
