A 85.3 kg ice skater is moving at 4.38 m/s
when she grabs the loose end of a rope, the op
posite end of which is tied to a pole. She then
moves in a circle of radius 0.564 m around the
pole.
Find the force exerted by the rope on her
arms. The acceleration of gravity is 9.8 m/s2 .
Answer in units of kN
