A man is sitting on a flat disc that is rotating. The disc mass is 200 kg, with a radius of 3 meters. He has a mass of 75 kg, and initially is sitting 2.5 meters from the center. Here he and the disc are rotating at 2.0 rad/sec. He wants to increase the angular velocity they rotate to 2.5 rad/sec, how far from the center should he move to, in meters? Note moment of inertia for the disk is (1/2)mr^2, and only the numerical answer needs to be typed in.*
