Two Skaters, Each of Mass 40 Kg, Approach Each Other

Multiple Choice

Two skaters, each of mass 40 kg, approach each other along parallel paths that are separated by a distance of 2 m. Both skaters have a speed of 10 m/s. The first skater carries a 2-m pole that may be considered massless. As he passes the pole, the second skater catches hold of the end. The two skaters then go around in a circle about the center of the pole.
-What is the angular speed of the skaters after they have linked together?

A) 4 rad/s
B) 5 rad/s
C) 10 rad/s
D) 20 rad/s
E) 40 rad/s
