A model airplane with mass 0.743 kg is tethered to the ground by a wire so that it flies in a horizontal circle 29.7 m in radius. The airplane engine provides a net thrust of 0.810 N perpendicular to the tethering wire. (a) Find the magnitude of the torque the net thrust produces about the center of the circle. 1 N · m (b) Find the magnitude of the angular acceleration of the airplane. 2 rad/s2 (c) Find the magnitude of the translational acceleration of the airplane tangent to its flight path. 3 m/s2
