Discussion Questions 1. Discuss the shapes of the x t, v t, and a t plots. Do these plots look sinusoidal? Are the frequencies (or periods) of the three plots the same? Do the maxima of the x, v, and a curves align, or is there a phase offset between them? Explain. 2. Discuss the shape of the F x parametric plot. Does the plot look linear? Explain why we expect this plot to be linear. What would a non-linear plot represent? 3. In this lab, you used two different experimental procedures to measure k. Explain both methods. How are they similar? How are they different? 4. What value of k did you measure with each methodology? Are these values consistent with each other? Why or why not? 5. Explainhowyoudeterminedyourmeasuredandcalculateduncertaintiesforbothmeth- ods. What led to these uncertainties? How could you reduce them
