An airplane is traveling at 150 m/s in level flight. If the airplane is to make a change in direction, it must travel in a horizontal curved path. To fly in the curved path, the pilot banks the airplane at an angle such that the lift has a horizontal component that provides the horizontal centripetal acceleration to move in a horizontal circular path. If the airplane is banked at an angle of 12.0 degrees, then the radius of curvature of the curved path of the airplane is
A. 10.8 km. B. 8.74 km. C. 8.00 km. D. 7.33 km. E. 6.90 km.
