what will be the new angular speed of the platform.
A thread is passing through a hole at the centre of frictionless table. At the upper end a block of mass 0.5kg is tied and a block of mass 8.0kg is tied at the lower end which is freely hanging. The smaller mass is rotate, on the table with a constant angular velocity about the axis passing through the hole so as to balance the heavier mass. If the mass of the hanging block is changed from 8.0kg to 1.0kg, what is the fractional change in the radius and the angular velocity of the smaller mass so that it balances the hanging mass again?

Suppose in the previous poroblem, the child stays at rest on the platform and one of hils firend throws a ball of mas m1 towards thim with a velocity of v from a direction tangential to the platform and the child on the platform catches the ball. Find the angular velocity of the platform after he catches the ball.

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.
