A model airplane with a mass of 0.748 kg is tethered by a wire so that it flies in a circle 30.2 m in radius. The airplane engine provides a net thrust of 0.806 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/s2

torque= force*radius

torque*radius= mass*radius^2 * angular acceleration

linear acceleraltion=angularacceleration*radius
