Two ice skaters hold hands and rotate, making one revolution in 2.90 s. Their masses are 57.0 kg and 72.0 kg, and they are separated by 1.30 m. Find the angular momentum of the system about their center of mass. Answer in kg m^2/s. If the skaters pull towards each other and decrease their separation to 0.80 m, what is the new period of rotation about the center of mass?

Two skaters, each of mass 40 kg, approach each other along parallel paths separated by 4.0 m. They have opposite velocities of 2.1 m/s each. One skater carries one endof a long pole with negligible mass, and the second skater grabs the other end of it as she passes. The skaters then rotate around the center of the pole. Assume thatthe friction between skates and ice is negligible.(a) What is the radius of the circle they now skate in?2 meters(b)...

Two ice skaters, with masses of 50.0 kg and 65.0 kg , are at the center of a 60.0 m -diameter circular rink. The skaters push off against each other and glide to opposite edges of the rink. If the heavier skater reaches the edge in 30.0 s , how long does the lighter skater take to reach the edge?

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,

cross product of the particle's instantaneous position vector
