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...

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...

An ice skater of mass m is given a shove on a frozen pond. After the shove, she has a speed of Vo = 2 m/s. Assuming that the only horizontal force that acts on her is a slight frictional force between the blades of the skates and the ice: Draw a free body diagram showing the horizontal force and the two vertical forces that act on her. Identify these forces. Use the work-energy theorem to find the distance the...
