) in an experiment on a damped spring oscillator with spring constant n/m, student c obtains the displacement vs time curves as in fig. 2(a), and records the maximum displacement data points as below. 1 2 3 4 5 (m) 0.0609 0.0488 0.0387 0.0299 0.0212 (s) 1.22 2.30 3.35 4.43 5.48 i. use eq. (9) to calculate the total energy and its natural logarithm from the data. ii. use excel to find the best-fit line of vs. . record the slope, -intercept, and in pre-lab. iii. from the best-fit line, find the characteristic dissipation rate
