Two skaters, each of mass 70 kg, skate at speeds of 4 m/s in opposite directions along
parallel lines 1.5 m apart. As they are about to pass one another they join hands and go
into circular paths about their common center of mass.
A third skater is skating at 2 m/s along a line parallel to the initial directions of the
other two and 6 m off to the side of the track of the nearer one. From his standpoint,
what is the total angular momentum of the other two skaters as they rotate?
