THe error is here:
angaccelearation=torque*r/mr^2
that bold r should not be there.
torque= I*angacceleration.
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.
(b) Find the angular acceleration of the airplane when it is in level flight.
angular acceleration = torque*r/mr^2=24.34(30.2)/(.748kg)(30.2)^2= 1.077 (I keep getting this part wrong. I got the torque right: torque= F*r = .806*30.2 = 24.34
