Calculate Elongation of Spring Given K, Mass & Density

[dban33]

Homework Statement

How do I find the elongation of a spring when just given K=119 N/m, mass of the wooden block it is attached to=4.17kg and the densty of the wooden block = 695 kg/m^3.

Homework Equations

I do not know what equation to use.

The Attempt at a Solution

I have not been able to make an attempt because I do not know what equation to start off with.

You had the correct equation the first time you posted the question.

Homework Equations

The equation I was trying to use was Fx=-kx
I do not think this is correct because my answer was wrong.

I'm curious why you multiplied 4.17 by 695?

Well I am trying to find the elongation of the spring. So the correct equation is F=-kx?
Does that mean that I change it to solve for x?? x= F/-k
I do not kno how to find the force for the equation if I only have the mass and density of the wooden block the string is attached to. I am completely lost!

The density of the wooden block has nothing to do with this problem.
