An airplane is flying in a horizontal circle at a speed of 390. km/h. If its wings are tilted at angle θ = 36.0° to the horizontal, what is the radius of the circle in which the plane is flying? Assume that the required force is provided entirely by an “aerodynamic lift” that is perpendicular to the wing surface. Use g = 9.81 m/s2.

An airplane is flying in a horizontal circle at a speed of 390. km/h (see the figure). If its wings are tilted at angle θ = 41.0° to the horizontal, what is the radius of the circle in which the plane is flying? Assume that the required force is provided entirely by an “aerodynamic lift” that is perpendicular to the wing surface. Use g = 9.81 m/s2.
