A solid sphere and a thin spherical shell, each of mass $m$ and radius $R$, are released simultaneously from rest at the top of identical ramps of height $h$ and inclination angle $\theta = 30^\circ$. The static and kinetic coefficients of friction between each object and its ramp are $\mu_s = \mu_k = 0.2$. Which has the greater total kinetic energy (translational plus rotational) when it reaches the bottom?
