Physics question for the radius

Question

What is the radius of turn for an airplane that is traveling at 42 m/s with a 35-degree bank angle?

Answer 1

Here the centripetal force counteracts the component of the plane's weight which opposes the centripetal force.

So, we would have

(mv²)/r = mgsinθ.

The masses cancel. That's why you are not given the mass of the plane. Isolate r and plug and chug.
