Circular Motion

[Haftred]

A review question for the test our teacher is going to give us is:

A 21,000 kg jet makes a 40 deg banked turn w/o losing altitude. Assume the life vector is perpendicular to the plane of the wings. What is the minimum radius turn it can execute at a speed of 200. m/s?

Any help appreciated.

Analyze the forces acting on the jet. Since it's turning, it is centripetally accelerated. (Consider the horizontal and vertical components of the forces.)
