A sphere of radius 2jx lg4jr*uy5pvuv3 /50.0 cm and mass 1.80 kg starts from rest and rolls withou 8q-yi4ibqcy5 o)h2/ b q5gmzzt slipping down a 3zqy/-4 2i hg5 mibqb5zoqc8 y)0.0 $^{\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?
