How to find Coeff of kinetic friction without mass?

[pierce_E]

Homework Statement

For my Physics lab this is what my teacher handed me... I have no idea how to attack the situation, can someone help solve?
Devise a procedure for an experiment which will measure the coefficient of kinetic friction between a block of unknown mass m and the table, where the only equipment which can be used is the following:
1) A string of negligible mass
2) two blocks of unknown identical masses which are able to be attached to string
3) a pulley
4) measuring tape(s)
Derive an expression for the coefficient of friction between the table and the block in terms of g and quantities measured with the equipment above.

Hello Pierce,

First post on PF and you bump into a culture issue: the guidelines require an attempt on your part.
List the equations that you think are relevant,
Describe some experiments that would help you determine relevant variables, etc.

And don't worry: mass might well divide away and thus drop out of the calculations.
