A Child Stands at the Centre of a Turntable with His Two Arms Outstretched. the Turntable is Set Rotating with an Angular Speed of 40 Rev/Min. How Much is the Angular Speed of the Child If He Folds His Hands Back and Thereby Reduces His Moment of Inertia to 2/5 Times the Initial Value? Assume that the Turntable Rotates Without Friction. - Physics | Shaalaa.com

Show that the moment of inertia of a uniform solid sphere rotating about a diameter is (2)/(5) M R^2. The sum (3.31) must be replaced by an integral, which is easiest in spherical polar coordinates, with the axis of rotation taken to be the z axis. The element of volume is d V=r^2 d r sinθd θd ϕ. (Spherical polar coordinates are defined in Section 4.8. If you are not already familiar with these coordinates, you should probably not try this problem yet.) | Numerade
