Two skaters skate toward each other, each moving at 3.3 m/s. their lines of motion are separated by a perpendicular distance of 1.5 m. just as they pass each other (still 1.5 m apart), they link hands and spin about their common center of mass. what is the rotational speed of the couple about the center of mass? treat each skater as a point particle, each with an inertia of 51 kg.
