I attached a photo of the problem and what I have done so far to help explain. I plotted an amplitude (given in the chart) vs. Force (calculated by mg of each mass because it is a vertical spring). I am not sure what to do next, I know the units of spring constant are N/m so I tried getting...
in the problem it says to use the line of best fit, so i thought the process would include using the averaged values. I don't really know where to start here.
I averaged the masses and times (which i took the time given and divided by 10 because in the problem it says you measure the time it takes to complete 10 oscillations) then plugged them directly into the T=(2(pi)((m/k)^1/2) and got the wrong answer. This is really confusing me because I don't...
