A model airplane with a mass of 0.751 kg is tethered by a wire so that it flies in a circle 29.7 m in radius. The airplane engine provides a net thrust of 0.797 N perpendicular to the tethering wire. (a) Find the torque the net thrust produces about the center of the circle. N-m (b) Find the angular acceleration of the airplane when it is in level flight. rad/s2 (c) Find the linear acceleration of the airplane tangent to its flight path. m/s
