A model airplane with mass 0.740 kg is tethered to the ground by a wire so that it flies in a horizontal circle 30.2 m in radius. The airplane engine provides a net thrust of 0.803 N perpendicular to the tethering wire.

(a) Find the magnitude of the torque the net thrust produces about the center of the circle.

N · m

(b) Find the magnitude of the angular acceleration of the airplane.

rad/s2

(c) Find the magnitude of the translational acceleration of the airplane tangent to its flight path.

m/s2
