John Salek-Raham D. Sarkar PHY 151 10/30/07 Lab M9: For the tabulated Data, see attached data sheet. V2: In this section of the experiment, varying masses were added to the bottom of the spring, and the resulting dimensions of the spring were measured relative to the starting position. m vs S y = 9.5272x + 1.3293 0 50 100 150 200 250 300 350 0 10 20 30 40 cm gm m vs S Linear (m vs S) Using excel, the slope of this graph, m vs S, was found to be 9.53. The spring constant can be found by multiplying the slope x 980 cm/sec^2. 9.53 g/cm x 980 cm/s^2 = 9339.4 dyne/cm

V3 In this section of the experiment, varying masses were added to the bottom of the spring and the number of oscillations made in 60 seconds was measured. T^2 vs m y = 0.0043x + 0.4602 0 0.2 0.4 0.6 0.8 1 1.2 1.4 1.6 1.8 0 100 200 300 gm s^2 T^2 vs. m Linear (T^2 vs. m) Using excel, the slope of the plot of T^2 vs. m was calculated to be 0.0043. Using the relationship: The spring constant was found to be 9171.7 dyne/cm. This is very close to the spring
