A ballet dancer spins about a vertical axis at 60 rpm with his arms closed. Now he stretches his arms such that M.I. Increases by `50%`. The new speed of revolution is

A dancer spins about a vertical axis at 60 rpm with her arms folded. If she strectes her hands so that M.I. about the vertical axis increases by 25% the new rate of revolvution is

A ballet dancer spins about a vertical axis at 2.5pi rad s^-1 with his arms outstretched. With the arms folded, the M.I. about the same axis of rotation changes by 25%.Calculate the new speed of rotation in r.p.m.

A ballet dancer spins about a vertical axis at 90 rpm with arms outstretched. With the arms folded, the moment of inertia about the same axis of rotation changes to 75 %. Calculate the new speed of rotation.

A ballet dancer revolved at 24 r.p.m. with her hands folded. If she stretches her hands so that her M.I. increases by 20%, then the new frequency of rotation will be

A ballet dancer spins about a vertical axis at 90 rpm with arms outstretched. With her arms folded, the M.I. about the axis of rotation decreases to 75%.Calculate the new rate of revolutions

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?
