A sphere of radius 20.0 cm and mass 1.80 kg starts from rest and rolls without slipping down a 30.0º incline that is
10.0 m long.
(a) Calculate its linear and rotational speeds when it reaches the bottom
(b) What is the ratio of linear to rotational KE at the bottom?
(c) do your answers in (a) and (b) depend on the radius of the sphere or its mass?
