Data ummary 8. Note that the graph shown here is Force vs Uni F Position. For a Hooke's Law spring, the graph of cart only Code F vs x results in a straight line, where the slope 1 mass + 4 . of that line is the spring constant. Does the Area: 0.33 N . m Elastic Cord used in this lab follow Hooke's Law? 2 mass W Area: 0.23 N . m 9. Use the Area tool to find the area under the Area: 0.32 N . m curve. You might need to use the Selection tool N to select only the part of the curve 10. What is the physical significance of the area? What are the correct units? Force (N 11.

Note that the 2.400 s, 0.98 m/s summary statistics are turned on showing the maximum, but you can also L.O 1.650 s, 0.90 m/s use the coordinates tool. 0.9 code 1.700 s, 0.93 m/s 13. Use this velocity and the mass of the cart to calculate the 0 8 kinetic energy of the cart. 0.7 14. Compare this to the work done by the Elastic Cord. What do 0.6 you conclude? 0.5 15. Repeat for the second run. Remember the mass changed! cart only Which of the following changed a lot from run one to run two, 0.4 and which did not change much at all? 1 mass Velocity (m/s 0.3 2 mass Work done by cord... 0.2 Change in cart kinetic energy...
