Reference no: EM13679477

Two children each of mass 20 kilogram ride on the perimeter of a small merry go round that is rotating at rate of 0.25 rev/s the merry go round is a solid disk of mass 30 kilogram and radius 3 meter. The children now both move halfway in toward the center positions 1.5 meter from the axis of rotation. Find final rate of rotation.
