A rubber stopper is twirled in a horizontal circle around your head for 20.0 cycles. How much work is done on the rubber stopper if you twirl the stopper with a speed of 3.0 m/s and the radius of the circle is 1.0 m? Assume the mass of the stopper is 50.0 g and it travels a distance of 20. cm during each cycle. * 1 point 0.0 J 9.0 J 100. J 180 J None of the above
