The Unknown Masses: For each unknown Determine the unknown masses, using the graphs of each spring that you have created. Indicate the appropriate points on each graph. It would be great to color coordinate if you can. Record all results in the table below. O Spring K-value Mass of green Mass of blue Mass of pink Strength unknown unknown (Slope Value) 4 10 Conclusions: 1 . The k-value of a spring can be found 2. What is interpolation? How was it used
