Question

there are 3 parts to this question. The weight is 100 grams.

[Q2-Home/Lab...) We attach a known weight (~100 gr) to a spring. By pulling down the spring by no more a couple of cm put it in oscillating mode. This experiment is described here [the screencast can be played in the PH 114-LABORATORY MANUAL, OSCILLALTIONS, UAH PHYSICS 2020-2021 classroom in mute as long as you keep an eye to spot the information you need]. Get the data from this experiment here. Based on the speed data: Q2.) Calculate the theoretical period and compare it to the observed period Qab) Calculate the maximum amplitude Q2.) Based on Qat, confirm the conservation of mechanical energy

Answer 1

a) Take two point with speed of same sign, any 0,= 24m/s; 3, 0.33m, Fi = -1.055N AF- 0.288 0.36m = ..767N An = 0.03 m 92 0.13 m/s ; *2 = Polo 0.85 S also can think about sign of :. 107- kloal =) K= 9.6 W/m WF rum V road/s = 9.798 road/s 180 X163 : Theoretical frequency for to an -1.56 Hz Froom data period is 0.3 comes twise =) Observed frequency = 0.85 after this time) fobseroved = 1.18 Hz /-) W = 7.39251 relocity (6) Amplitude, A, then, equation of motion will be -0.3 + Asinat (because attoo t = 0.2, (wt) in degree is, = 7139 2X 0.2 x 480 = 84.70 6° & (0.2) = 0.35 = 0.3+ Asin 184•706) - 0.05 no.05 m (lowest re highest &e.) e n = 0.3m) Whent 7T sin/84•706 But from observation, A= 10.37 0.28 (c) Total Total energy enerogy mw2A = 5.532 X10-33
