A model airplane with mass 0.750 kg is tethered to the ground by a wire so that it f lies in a horizontal circle 30.0 m in radius. The airplane engine provides a net thrust of 0.800 N perpendicular to the tethering wire. (a) Find the torque the net thrust produces about the center of the circle. (b) Find the angular acceleration of the airplane. (c) Find the transla-tional acceleration of the airplane tangent to its f light path.
