A boy swings a ball on a string around his head in a circle. Starting out, the radius is ro and the speed is vo. But then he pulls the string in until the radius is rf. These are the numbers: ro = 10 meters rf = 6 meters vo = 6 m/s Suppose that the speed is constant as he pulls the string in. Calculate the final force divided by the initial force (Ff/Fo).
