A sphere of radius 20.mmdrl:9/v l 6e0 c8k s8 wuv.hnsym*m;f b bso6;3m and mass 1.80 kg starts from rest and rolls without slipping down a 30.0*sykv ; ;s.3nw6ommu8f8hs bb $^{\circ} $ incline that is 10.0 m long. (a) Calculate its translational and rotational speeds when it reaches the bottom. $v_{CM}$ = $\omega$ = $rad/s$ (b) What is the ratio of translational to rotational KE at the bottom? Avoid putting in numbers until the end so you can answer: (c) do your answers in (a) and (b) depend on the radius of the sphere or its mass?
