A 54.4 kg ice skater is moving at 3.95 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 0.790 m around the pole.

(a) Determine the force exerted by the horizontal rope on her arms.
N

(b) Compare this force with her weight by finding the ratio of the force to her weight.

    Wilhelmina is an avid ice skater who is also taking physics with her friend Darcy. Wilhelmina is having a discussion with Darcy and is trying to relate her skating experience to the discussions in class about rotational kinetic energy and angular momentum. Darcy reminds Wilhelmina that the instantaneous angular momentum, , of a particle relative to an axis through an origin O is defined by the cross product of the particle's instantaneous position vector relative to O, , and its...

    A 57.7 kg ice skater, moving at 15.4 m/s, crashes into a stationary skater of equal mass. After the collision, the two skaters move as a unit at 7.7 m/s. Suppose the average force a skater can experience without breaking a bone is 4520 N. If the impact time is 0.11 s, what is the magnitude of the average force each skater experiences? Answer in units of N.
