You throw a frisbee of mass m = 0.5 kg, and radius
r = 0.1 meters, off of a hill, with initial translational
speed of v0 = 5 m/s, from a height of
h0 = 3 meters. The tangential speed of the edge
of the frisbee is equal to the initial translational speed, and
doesn't change as it travels through the air. Treat the frisbee as
a solid disk, and ignore air resistance.
