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 moves along a chord of the platform with a constant velocity (with respect to the platform), the angular velocity of the platform will vary with time t as -

A circular plarform 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), the angular velocity of the platform omega(t) will vary with time t as

A circular disc is rotating in horizontal plane about vertical axis passing through its centre without friction with a person standing on the disc at its edge. If the person gently walks to centre of disc then its angular velocity

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 person of mass m stands at the edge of a circular platform of radius R and moment of inertia. A platform is at rest initially. But the platform rotate when the person jumps off from the platform tangentially with velocity u with respect to platfrom. Determine the angular velocity of the platform.
