A model airplane with a mass of 0.745kg is tethered with a wire so that it flies in a circle 29.4 m in radius. The airplane engine provides a net thrust of 0.795 N perpendiculars to the tethering wire.
1) Discover the torque the net thrust produces about the center of the circle.
2) Find the angular acceleration of the airplane when it is in level flight.
3) Discover the linear acceleration of the airplane tangent to its flight path.
