Suppose you wish to determine the spring constant experimentally. You hang multiple masses from a spring of choice and measure the displacement of some point on the spring from equilibrium. Next, you plot the force applied to spring on the vertical axis (weight the spring is supporting) against the corresponding stretch of the spring (from equilibrium) on the horizontal axis you may get a plot as that shown below: 5.5 5.0 4.0 Force [N] 2.0 2 3 4 5 .6 8 9 10 11 12 13 14 1.6 Stretch [m] Using the purple trendline, estimate what the spring constant of the spring is. Give your answer in units of N/m, however do not include the units explicitly in your answer. If you include units, the answer will be counted wrong
