1. The problem statement, all variables and given/known data A 72.8 kg ice skater is moving at 5.01 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 0.765 m around the pole. The acceleration of gravity is 9.8 m/s2 . Find the force exerted by the rope on her arms. Answer in units of kN = 2.3886108 kN Find the ratio of this tension to her weight. 2. Relevant equations Fc = mv^2 / R W=mg 3. The attempt at a solution Fc = mv^2 / R Fc = (72.8)(5.01)^2 / .765 Fc = 2388.6108 N Fc = 2.3886108 kN It's the ratio that's getting me, shouldn't it just be: 2.3886108 kN / (72.8 x 9.8) =.003348 But the ratio is wrong? Please help.
