## Homework Statement

A constant horizontal force F

_{app}of magnitude 10N is applied to a wheel of mass 10kg and radius .3m. The wheel rolls smoothly on the horizontal surface, and the acceleration of its center of mass has magnitude .6 m/s

^{2}(a) In unit-vector notation, what is the frictional force on the wheel? (b) what is the rotational inertia of the wheel about the rotation axis through its center of mass?

## Homework Equations

I don't even know

## The Attempt at a Solution

I spent more than an hour on this and I could not figure it out. Needless to say I am extremely frustrated because it seems as though my teacher has not taught us anything we need to know to solve this, so I don't think any of my work is worth typing in this space.
