Basic physics

  1. Nov 8, 2008 #1
    1. The problem statement, all variables and given/known data
    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.

    2. Relevant equations
    I do not know what equation to use.

    3. 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.

    I'm curious why you multiplied 4.17 by 695?

    Well im 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.
