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.

  1. A uniform hollow spherical ball of mass 1.75 kg and radius 40.0 cm rolls without slipping up a ramp that rises at 30.0° above the horizontal. The speed of the ball at the base of the ramp is 2.63 m/s.
    (a) While the ball is moving up the ramp, find the magnitude of the acceleration of its center of mass
