A sphere of radius 20.0 cm m5r,0qj mxaifad:l 69and mass 1.80 kg starts from rest and rolls 72nzo3cbtmd63cx9(t dk* 1 ct/pbveswithout slipping down a 30.0 ct 9 v 3pt7z3ct*b( 6oebxndkd c2s/m1$^{\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?
