How to find friction force?

In my recent experiment I was given only the mass. The mass is 0.0954kg.

This mass is on a horizontal plane and is attached by a string over a pulley and just enough mass was added to the end of the string so the system would start moving with constant velocity.

I know the net force on each mass is 0 since the acceleration is 0.
So I'm confused as to how I should calculate the friction force.

Then I need to calculate muk, which I would know how to do if I had the friction force!

Any help is really appreciated!!
