A model airplane having a mass of 0.743 kg is tethered by a wire so that it flies in a circle 30.8 m in radius. The airplane engine provides a net thrust of 0.802 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
i need to know by tonight! if you can got the right answer, i'll give you best answer asap!

-
a) torque = forece x radius = 30.8x0.802 = 24.7016 Nm
b) torque = I x angular acceleration and I = m r^2 = 0.743x (24.7016)62 = 0.4779
angular acceleration = torque/ I = 51.68774 rad/s^2
c)linear acceleration, a = angular acceleration x r = 51.68774 x 0.802 = 41.45357 m/s^2
DONE!!! now have some fun:
