A sphere of radius 20.0 cm and mass cmtzk2 ;1;-eue3h7so (qm v g3zanw1j1.80 kg start8 p5avuvp8 gm, ycxl3;c0v.r ws from rest and rolls without slipping down a 30.0v83ucvx, y0.5;pmwvac8p rlg $^{\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?
