Finding Acceleration of Gravity for Springs Without a Given K

    Finding Acceleration of Gravity for Springs Without a Given "K"

    1. The problem statement, all variables and given/known data

    What I need is to gather data for the period, displacement, and mass of a certain object put on a spring. Later, I was asked to find the gravity--however I wasn't given a spring constant and I'm left on my own. I haven't been able to successfully calculate a spring constant and acceleration of gravity (I've tried to do this since Monday). For example:

    I have:
    Period: .96s
    Mass: 100g
    Displacement: 45cm


    2. Relevant equations

    F=-kx

    T=2[itex]\pi[/itex][itex]\sqrt{m/k}[/itex]

    3. The attempt at a solution

    I thought I could solve for K using the Period of a Mass-Spring System equation (T=...), however, it seems I can't... so I'm a bit lost.

    What is "displacement"?

    Why can't you find k given the period and the mass?
