Finding kinetic coefficient of friction (pulley involved)

[ccsmarty]

Homework Statement

A wooden block with mass 0.1305kg is sitting on a horizontal dynamics track. The block is attached to a counterweight of mass 0.050kg by means of a frictionless pulley (the counterweight is hanging off of the table). The system is released from rest, and after traveling 0.8 meters, the velocity of the block is 0.5767 m/s. Calculate the coefficient of kinetic friction
