Although never the case, assume the rotating stage at the fashion event is free to rotate. There appear to be five performers at an outer radius of 4 feet and two performers towards the center at a radius of 0.5ft. Take the stage to be a 1deltadeltadelta.delta lb disk with a 6-ft radius and presume the performers weigh 120lb each. If the disk is originally gliding at a rotational speed of 5 rev/min, determine the new rotational velocity if the two performers near the center move out to the 4foot radius of the other performers.
