A uniform horizontal circular platform of mass `200 kg` is rotating at 10 rpm about a vertical axis passing through its center. A boy of mass `50 kg` is standing at its edge. If the boy moves to the center of the platform, the frequency of rotation would become

A uniform horizontal circular platform of mass 200kg is rotating at 5 rpm about vertical axis passing through its centre. A boy of mass 80kg is standing at its edge. if boy moves to centre of platform, find out final angular speed

A circular platform is free to rotate in a horizontal plane about a vertical axis passing through its centre. A tortoise is sitting at the edge of the platform. Now the platform is given an angular velocity omega_(0) . When the tortoise move along a chord of the platform with a constant velocity (with respect to the platform),
