An airplane is traveling at 150 m/s in level flight. In order to make a change in direction, the airplane travels 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 radial 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.

Question

Quizplus · Accepted Answer

The correct answer is A because the radius of curvature of the curved path of the airplane is 10.8 km. This is because the horizontal component of the lift provides the horizontal radial acceleration to move in a horizontal circular path, and the angle of bank is 12.0 degrees.
