A flat uniform circular disk (radius = 2.60 m, mass = 1.00 x 102 kg) is initiallystationary. The disk is free to rotate in the horizontal planeabout a frictionless axis perpendicular to the center of the disk.A 40.0 kg person, standing 1.80 m from the axis, begins to run on the disk in acircular path and has a tangential speed of 2.30 m/s relative to the ground.
Find the resulting angular speed of the disk (in rad/s)
