The question ask for me to find the force of friction between the ramp and the sphere.

My attempt at the problem was to utilize the x-component of the force of gravity of the sphere and then the friction must be greater than that component.

I also have a feeling to use final energy - initial energy = nonconservative work, but I can't seem to find a velocity, whether its linear or angular, which is necessary to find the energy.

Note: when a ball rolls without slipping, v=R * [tex]\omega[/tex]

Thank you for your time.
