A spherical object (with non-uniform density)

of mass 30 kg and radius 0.22 m rolls along a

horizontal surface at a constant linear speed

without slipping. The moment of inertia of

the object about a diameter is 0.56 M R2.

The object’s rotational kinetic energy

about its own center is what fraction of the

object’s total kinetic energy?
