Write out formula and substitution (the first picture is the data)

2. Calculate the spring constant for each device that obeyed Hooke's Law utilizing graphical analysis. (Find the slope of the line.) SPRING ' RUBBER BAND . For the SPRING, calculate the area under the graph to determine the total 'work done: Now, calculate the total work done for the SPRING by using PEs =%k b 5. Calculate the percent error for the total work done: [ calculated area = measured value AND PEs = accepted value ] 6. How do you account for the difference? 2. For your SPRING, use the Potential Energy of a spring formula to calculate the work done stretching it a distance of 0.1 meters and then stretching it a distance of 0.2 meters. How does the work done in these two cases compare? AN 3. For your SPRING, use the Potential Energy of a spring formula to calculate the work done if the spring constant is double the original spring constant. (Be sure to use the same value for the stretch that you used in ANALYSIS SECTION, # 4) How does the work done in this case compare to the original work done on the spring
