Globe of radius 0.10 m spinning about a vertical axis, a dot on its equator
Globe of radius 0.10 m spinning about a vertical axis, a dot on its equator
A miniature, solid globe with mass \(0.25\,\text{kg}\) and radius \(0.10\,\text{m}\) is spinning in place about a vertical axis with the equator horizontal, as shown. A point on the globe’s equator, represented by the dot in the figure, has a linear speed of \(4.0\,\text{m/s}\). The rotational inertia of a solid sphere of mass \(m\) and radius \(r\) is \(\dfrac{2}{5}mr^{2}\). The rotational kinetic energy of the globe is most nearly
