Slipping Shell

rotationMedium
A solid sphere and a thin spherical shell, each of mass mmm and radius RRR, are released simultaneously from rest at the top of identical ramps of height hhh and inclination angle θ=30∘\theta = 30^\circθ=30∘. The static and kinetic coefficients of friction between each object and its ramp are μs=μk=0.2\mu_s = \mu_k = 0.2μs​=μk​=0.2. Which has…
