A sphere of radius 20.0 cm and masbvs t:9tf(hp9/gwhl -s 1.80 kg starts fro5yud (b2li9-qawan u .9yfz) cm rest and rolls without slyblq2df n.au-9 zacw9 u)(y5i ipping down a 30.0 $^{\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?
