A child with mass `m` is standing at the edge of a merry go round having moment of inertia `I`, radius `R` and initial angular velocity `omega` as shown in the figure. The child jumps off the edge of the merry go round with tangential velocity `v` with respect to the ground. The new angular velocity of the merry go round is

A child with mass m is standing at the edge of a disc with moment of inertia I , radius R m and initial angular velocity omega . See figure given below. The chlid jumps off the edge of the disc with tangential velocity v with respect to the ground. The new angular velocity of the disc is. .

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.

A child is standing on the edge of a merry-go-round that has the shape of a disk, as shown in the figure. The mass of the child is 40 kg. The merry-go-round has a mass of 200kg and a radius of 2.5 m, and it is rotating with an angular velocity of omega=2.0 radians per second. The child then walks slowly towards the centre of the merry-go-round. What will be the final angular velocity of the merry-go-round when the child reaches the centre? (The size of the child can be neglected)

A flat car of mass M is at rest on a frictionless floor with a child of mass m standing at its edge. If the child jumps off from the car towards right with an initial velocity u , with respect to the car, find the velocity of the car after its jump.
