If a spherical ball rolls on a table without slipping, the fraction of its total kinetic energy associated with rotation is 2/7. This fraction is derived by comparing the rotational kinetic energy, which depends on the moment of inertia of the sphere, to the total kinetic energy, which is the sum of both rotational and translational kinetic energies.
If a spherical ball rolls on a table without slipping, the fraction of its total energy associated with rotation is ______?
