## Homework Statement

A constant horizontal force app of magnitude 15 N is applied to a wheel of mass 8.9 kg and radius 0.39 m. The wheel rolls smoothly on the horizontal surface, and the acceleration of its center of mass has magnitude 0.76 m/s2. (a) What is the magnitude of the frictional force on the wheel? (b) What is the rotational inertia of the wheel about the rotation axis through its center of mass?

## The Attempt at a Solution

I don't even know where to begin for either part. For (b) I tried using several rotational inertia equations; however, none of the ones I used worked.
