Part 2 - Investigating Newton's second law [1] Use the linear fit from Graph 4 to determine your experimental value for g with uncertainty. g = (_ + [1] Compare your value of g with the accepted value of 9.81 m/s2. Calculate the percentage difference %diff = accepted - Jexperimental x 100, gaccepted and discuss. [1] In the linear fit of Graph 4, what is the physical meaning of the Y-intercept value? [1] Do your results agree with Newton's 2nd law?Latest Position vs. time on an incline Time Position Velocity (S) (m) (m/s) 0.25 0.178 0.002 1.0 0.30 0.177 -0.001 0.35 0.177 0.000 0.40 0.177 0.000 0.45 0.177 0.001 0.8 0.50 0.177 0.000 Auto Fit for: Latest | Position x = A*t^2+Bt+C 0.55 0.177 0.000 A: -0.04836 +/- 4.255E-05 0.60 0.177 0.000 B: 0.5729 +/- 0.0005122 Position (m) 0.65 0.000 0.6- 0.177 C: -0.6517 +/- 0.001381 0.70 0.177 0.000 Correlation: 0.9999 RMSE: 0.002730 m 15 0.75 0.177 0.000 16 0.80 0.177 .000 0.4- 17 0.85 0.177 0.000 18 0.90 0.177 0.000 19 0.95 0.177 0.001 20 1.00 0.178 0.002 0.2 21 1.05 0.178 -0.002 22 1.10 0.177 -0.003 10 23 1.15 0.177 -0.001 Time (s) 24 1.20 0.177 -0.001 25 1.25 0.178 -0.010 26 1.30 0.176 -0.011 Velocity vs. time on an incline 27 1.35 0.176 -0.001 28 1.40 0.176 0.005 29 1.45 0.177 0.005 30 -0.013 0.4 1.50 0.178 31 1.55 0.176 -0.032 32 1.60 0.172 0.002 33 1.65 0.174 0.085 X 34 1.70 0.177 0.231 0.2 Linear Fit for: Latest | Velocity 35 1.75 0.198 0.359 v = mt+b m (Slope): -0.09637 +/- 0.0002013 m/s/s 36 1.80 0.218 0.393 b (Y-Intercept): 0.5725 +/- 0.001284 m/s 37 1.85 0.238 0.400 Velocity (m/s) Correlation: -0.9996 38 1.90 0.258 0.395 O.
