A model airplane with mass 0.750-kg is tethered by a wire so that it flies in a circle of radius 30.0-m. The airplane engine provides a force of 0.800-N perpendicular to the tethering wire. (Consider the airplane to be a point mass)
(a) Find the torque that the net thrust produces about the center of the circle.
(b) Find the angular acceleration of the airplane.
(c) Find the linear acceleration of the airplane tangent to its flight path.
