flies, the wind applies a constant moment, causing the frisbee to rotate faster. If the frisbee was initially
at rest, determine the moment of the wind and the work done by said moment. Assume the frisbee can be
modelled as a disk with mass m = = 0.15 kg and that it rotates about its center of gravity G. The frisbee has
