(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I gathered the following data in an experiment:

Trial Mass (kg) Stretched Spring (m) Force (N) Highest Point (m) Lowest Point (m)

1 .05 .05 ? 0 .09

2 .1 .095 ? .015 .185

3 .25 .245 ? .065 .45

In the experiment i attached different weights to a spring and measured the spring first as it was stretched and I then released the spring to see the highest and lowest points. I now am supposed to calculate the force in Newtons for each trial.

2. Relevant equations

F=ma I know is the equation for force but how is it applicable to this data? I understand m would be equal to the mass of the object in kg, but how would I find a for the equation?

3. The attempt at a solution

I originally thought that I would use the stretched spring as a, but now I am not so sure, would I use the change in the highest and lowest point instead? however, acceleration really doesn't apply here so I am confused.
