Notes Ask Your A 54.0-kg ice skater is moving at 4.08 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 0.900 m around the pole. (a) Determine the magnitude of the force exerted by the horizontal rope on her arms. Your response is off by a multiple of ten.kN (b) Compare this force with her weight. Frope-1.8854 Noed Help?

Explanation / Answer

6.A. Force F=mv2/r = 54x(4.082)/0.9 N = 998.784 N = 0.998784 kN

B. F/W= 998.784/mg =998.784 /(54x9.8) = 1.8873
