[SOLVED] Force for uniform circular motion 1. The problem statement, all variables and given/known data A 61.7 kg ice skater is moving at 3.55 m/s when she grabs the loose end of a rope, the opposite end of which is tied to a pole. She then moves in a circle of radius 0.545 m around the pole. The acceleration of gravity is 9.8 m/s^2. a. Find the force exerted by the rope on her arms. Answer in units of kN. b. Find the ratio of this tension to her weight. 2. Relevant equations F=(mv^2)/r 3. The attempt at a solution I got a using the above equation: F=((61.7) * (3.55)^2)/.545 F=1426.74 N or 1.42674 kN I know this is right for part a, I just don't understand what they are asking for part b or what equation to use. I would appreciate any help.
