Two children sit opposite each other on a horizontal merry-go-round. The little boy weighs 40 pounds and sits 1.0 m from the center of the equipment. The little girl weighs 25 pounds and also sits 1.0 m from the center of the thing. Dad gets them going and climbs a nearby tree and crawls out onto a limb overhanging the merry-go-round to take some pictures. As dad sees the children they are turning in a clockwise way with constant speed.
The angular velocity of the little girl is ___.
