Find how far the spring will be stretched

  1. Feb 3, 2013 #1
    1. The problem statement, all variables and given/known data

    A spring is stretched by a force of 0.80n a distance of 0.012m. Find how far it will stretch when the force is 0.54n.

    One problem is that I don't know how to find k.

    2. Relevant equations

    F=kΔd

    3. The attempt at a solution

    F=kΔd
    F=k(0.012m)
    What is k?

    F=kΔd

    so

    k = F/Δd

    Wow...
    I can't believe I didn't think of that. Thank you!
