A 55.0-kg ice skater is moving at 4.00 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 0.800 m around the
pole. (a) Determine the force exerted by the horizontal rope
on her arms. (b) Compare this force with her weight.


Expert Answer

Step 1

The formula for the force exerted ...
