A circular platform of radius Rp = 4.00 m and mass Mp= 400. kg rotates on frictionless air bearings about its vertical axis at 6.00 rpm. An 80.0-kg man standing at the very center of the platform starts walking (at t = 0) radially outward at a speed of 0.500 m/s with respect to the platform. Approximating the man by a vertical cylinder of radius Rm = 0.200 m, determine an equation (specific expression) for the angular velocity of the platform as a function of time. What is the angular velocity when the man reaches the edge of the platform?
