A hokey tablet of mass m is tied to a rope that runs through the center of a table. The pill moves in a circle of radius r. At the other end of the rope hangs a mass m. Consider that the
table surface is perfectly smooth. What is the expression of the speed of the hokey pickup
if the mass m remains at rest?
