[1.5 pts] {Section B} (a) Make a graph of force vs. holder height, and include error bars on your plot.Draw the best straight line through your points. (b) From the slope of the line(s) in the graph in (b), report the spring constant of the springwith uncertainty. . [1.0 pts] {Section B} Using your reported value and uncertainty for the spring constant, predict the period of oscillation for your spring with a 70 gram mass attached to its bottom end. Part B: Measure the spring constant for your spring Masses (no uncertainty): 50g, 70g, 90g, 110g, 130g. Holder heights (with uncertainty): (30.85470.1141)cm, (27.93030.1217)cm, (25.00580.1071) cm, (22.0814+0.1291)cm, (19.1569+0.0779) cm. Part C: Measure the period of oscillation as a function of mass mass = 50g A = 2.2942 0.066 cm B = 10.5872 0.0366 rad/s C = 3.0395 1.3776 D = 39.2273 0.0713 cm mass = 70g A = 2.6694 B = 8.937 C = 3.2911 1.9088 D = 35.7669 0.0717 cm 0.1031 cm 0.0561 rad/s mass = 90g A = 2.8468 0.1366 cm 0.0483 rad/s B = 7.9043 C = 3.6566 1.8383 D = 32.1995 0.0882 cm mass = 110g A = 2.0889 0.0855 cm B = 7.1371 0.0602 rad/s C = 2.8773 2.0386 D = 28.6807 0.0863 cm mass = 130g A = 3.0195 0.0787 cm B = 6.5727 0.0448 rad/s C = 2.8437 1.6978 D = 25.217 + 0.0743 cm
