## Homework Statement

Find the coefficient of kinetic friction between a 4.3- block and the horizontal surface on which it rests if an 89 spring must be stretched by 2.3 to pull the block wi`th constant speed. Assume the spring pulls in a direction 15 above the horizontal.

## Homework Equations

Fk = [tex]\mu[/tex]kN

## The Attempt at a Solution

I'm completely lost on this one, I don't understand how to find anything with the spring to convert it to a Normal force.
