Academics

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?

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