**Simple Harmonic Motion**

have performed an experiment of simple harmonic motion and the values I got Mass(g) Distance (m) 200 0.438 250 0.398 300 0.345 350 0.312 400 0.297 450 0.281 500 0.259 I would like to know how to calculate the spring constant... since I have been having weird values, if ...
