A hollow spherical shell with mass 2.45kg rolls without slipping down a slope that makes an angle of 30.0∘ with the horizontal. a.) find the magnitude of the acceleration of the center of mass of the spherical shell. b.) find the magnitude of the frictional force acting on the spherical shell.
I know that the center of mass for a hollow sphere is 2/5mr^2 and since the sphere is not slipping v=wR (w=omega) and a=(alpha)*r but I'm not sure how to approach this question.
