the skaters then rotate around the center of the pole. assume that the friction between skates and ice is negligible. what are (a) the radius of the circle, (b) the angular speed of the skaters, and (c) the kinetic energy of the two-skater system? next, the skaters pull along the pole until they are separated by 1.0 m. what then are (d) their angular speed and (e) the kinetic energy of the sy
