thanks for that. hmmm- I am assuming the angular momentum in both cases is the same. I worked out the moment of inertia of the object at the bigger radius. I = mr /2 (0.870)(7.8/2) 52.9308 angular momentum = (52.9308)(9.85) = 521.37 any idea on where to go from here??

A small 0.870-kg object moves on a frictionless horizontal table in a circular path of radius 7.80 m. The angular speed is 9.85 rad/s. The object is attached to a string of negligible mass that passes through a small hole in the table at the center of the circle. Someone under the table begins...
