A dancer spins about himself with an angular speed `omega`, with his arms extended. When he draws his hands in, his moment of inertia reduces by 40% . Then his angular velocity would be

A child is standing with his two arms outstretched at the centre of a turntable that is rotating about its central axis with an angular speed omega_0 . Now, the child folds his hands back so that moment of inertia becomes 3 times the initial value. The new angular speed is.

A ballet dancer spins about a vertical axis at 120 rpm with arms out stretched. With her arms fold the moment of inertia about the axis of rotation decreases by 40% . What is new rate of revolution?

A jester in a circus is standing with his arms extended on a turntable rotating with angular velocity c. He brings his arms closer to his body so that his moment of inertia is reduced to one third of the original value. Find his new angular velocity [Given: There is no external torque on the turn table in the given situation.]

A person is standing on a rotating table with metal spheres in his hands. If he withdraws his hands to his chest, then the effect on his angular velocity will be.

An ice skater spins at 3pi" rad s"^(-1) with hers arms extended. If her moment of inertia with arms folded is 75% of that with arms extended, her angular velocity when she fold her arms is
