Finding coefficient of kinetic friction when a mass overcomes pulley friction

[sugarntwiligh]

How do I find the coefficient of kinetic friction for a pulley?
F=mueN
If a mass of 0.019 kg overcomes the friction in a pulley, is this mue?
Normal force would be 0.20 kg * 9.8?

But it can't be mue, because I am asked to find mue in the question.

Hi sugarntwiligh!

(have a mu: µ )

What is the set-up?

Can you tell us the full question?
