1. The problem statement, all variables and given/known data

I have a plot whose vertical intercept is 0.00352 [Nm]
If the bearings are 2 [mm] from the center of the wheel,
then what is the force of friction?
Use three significant figures for your answer in Newtons.

2. Relevant equations

Torque= (Rotational Inertia)(Angular Acceleration)+ Torque due to friction


3. The attempt at a solution
Torque=0.00352Nm
Torque due to friction = (Rotational Inertia)(Angular Acceleration) - Torque
Tf= (I)*(A)-0.00352Nm

I don't even know how to attempt to solve for those other variables. Is this even the right equation to use?
