Homework Equations
Hooke's Law
F=kx
The Attempt at a Solution
(m1+m2)g/x=k
(.045kg+.055kg)9.8m/s^2/m = k
but this isn't right, I don't think.
I'm not sure what I'm missing, but it seems that I don't have all the information correctly utilized. Hooke's law, though, is the only thing I could think to use with the given information and based upon what we need to find.
any help would be greatly appreciated, as I need this information for my laboratory experiment.
