A preson is standing on the centre of a rotating table with his arms outstretched. The table is rotating freely with an angular his hands towards his chest. The moment of inertia reduces to `(3)/(5)` time the original moment of inertia. Calculate angular speed of the man when he withdraws his hands.

A man standing at the centre of a rotating table, with his hands stretched outwards. The table is rotating at the rate of 30 rev/minute. If the man brings his hands towards his chest and thereby reduces his moment of inertia to (3)/(5) times of its original moment of inertia, then the number of revolutions performed by the rotating table per minute will be

A child stands at the turn table center of a turnable with his two arms outstretched. The turnable is set rotating with an angular speed of 10 rad//s . If the child folds his hands back so that the moment of inertia reduces to 3//5 times the initial value, find the new angular speed. Why does the kinetic energy of child increase?

A man is sitting on a rotating stool with his arms outstretched. If suddenly he folds his arms the angular velocity of the man would

A child stands at the centre of a turn table with his two arms outstretched. The turn table is set rotating with an angular speed of 40 rpm. How much is the angular speed of the child, if he folds his hands back reducing the moment of inertia to (2//5) time the initial value ? Assume that the turn table rotates without friction. (b) Show that the child's new K.E. of rotation is more than the initial K.E. of rotation. How do you account for this increase in K.E. ?
