A thin spherical shell of mass \(0.60 \text{ kg}\) and radius \(0.15 \text{ m}\) rolls without slipping along a horizontal surface with a constant translational speed of \(2.0 \text{ m/s}\). The rotational inertia of the spherical shell about its center of mass is \(I = \dfrac{2}{3}MR^2\). What is the rotational kinetic energy of the sphere?
