Calculations and Analysis A. For each data row in each of your tables calculate: Elastic PE = I believe it is 1/2kx^2, so I used PE= 1/2kx^2 for the calculations. B. For each spring and the rubber band, plot the accumulated elongation (X-axis) versus the applied force (Y-axis) on a computer spreadsheet.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
