Suppose a person of mass `m` stands at the edge of a circular platform of radius `R` and moment of inertia `I`. The platform is at rest initially, but the platform begins to rotate when the person begins to move with velocity `v`. Determine the angular velocity of the platform.

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.

Consider the situation of previous example. If the platform is rotating intially with angular velocity omega_(0) and then person jumps off tangentially. Determine the new angular velocity of the platform.

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.

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.

A kid of mass M stands at the edge of a platform of radius R which can be freely rotated about its axis. The moment of inertia of the platform is I . The system is at rest when a friend throws as ball of mass m and the kid catches it. If the velocity of the ball is v horizontally along the tangent to the edge of the platform when it was caught by the kid find the angular speed of the platform after the event.

A kid of mass M stands at the edge of a platform of radius R which can be freely rotated about its axis. The moment of inerti of the platform is I . The system is at rest when a friend throws as ball of mas mand the kid cathces it. If the velocity of the ball is v horiontally along the tangent to the edge of the platform when it was caught by the kid find the angular speed of the platform after the event.

A insect of mass m stands on a horizontal disc platform of moment of inertia 1 which is at rest. What is the angular velocity of the disc platform when the insect goes along a circle of radius r, concentric with the disc, with velocity v relative to the disc.

A train goes past a person standing at the edge of a platform at high speed. Then the person will be
