A child of mass m is standing
A child of mass m is standing, on the periphery of a circular platform of radius R, which can rotate about its central axis. The moment of inertia of the platform is I. Child jumps off from the platform with a velocity u tangentially relative to the platform. Find the angular speed of the platform after the child jumps off.

Initially the platform with the child is rotating with an angular speed ω 1 . If the child starts walking along its periphery in opposite direction with speed u relative to the platform ,
on the periphery of a circular platform of radius R ,
what will be the new angular speed of the platform. ,
