Two children are riding on the edge of a merry-go-round that has a mass of 100.kg and radius of 1.60m and is rotating at 20.0rpm (disc). ignore friction. the children have masses of 22.0kg and 28.0kg and are seated on the outside (simple pendulum). if both children move to half the radius (0.8m) what is the new rotational speed?
