Question
(II) A sphere of radius r=34.5 cm and mass m=1.80 kg
starts from rest and rolls without slipping down a 30.0°
incline that is 10.0 m long. (a) Calculate its translational
and rotational speeds when it reaches the bottom. (b) What
is the ratio of translational to rotational kinetic energy 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?
