Question

Consider a level flight turn of a propeller-driven 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
