An ice skater of mass m = 60 kg coasts at a speed of v = 0.71 m/s past a pole

 Darcy and Wilhelmina now tackle a homework problem.


 An ice skater of mass m = 60 kg coasts at a speed of v = 0.71 m/s past a pole. At the distance of closest approach, her center of mass is r1= 0.37 m from the pole. At that point she grabs hold of the pole.


 (A) What is the skater's angular speed when she first grabs the pole?

 _______ rad/s

 (B) What is the skater's angular speed after she now pulls her center of mass to a distance of r2= 0.16 m from the pole?

 _______ rad/s

    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...
