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

A mass attached to a holder hangs from a spring. the combined mass of the hanger, spring, and mass=45g. Adding mass of 55g stretches the spring 12cm. What is the spring constant?

2. Relevant equations

Hooke's Law

F=kx

3. 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.
