a 82.7 kg ice skater is moving at 5.88 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 0.627 m around the pole. the acceleration of gravity is 9.8 m/s^2. Find the force exerted by the rope on her arm.

  1. The centripetal force, which is applied by the rope, would be M V^2/R, where R is the length of the rope. The value of g does not affect that force, but it does affect her weight on the ice.
