Another (slightly better) way would be to plot the velocities $v_{mid}$ vs time and take a least-squares linear regression line, as KvdLingen said. You will get a similar number with this method, but because it uses a slightly different method to find the average (least squares vs arithmetic), some people find it preferable. | |

| Mar 9, 2014 at 15:42 | comment | added | scribblemaniac | Thank you for the "wall of text", I enjoyed learning about the effect that uncertainty had on the results. I knew there would be some uncertainty in the calculations, but I never guessed that it would have made such a large impact on the numbers! I will try to follow your suggestions to attain numbers with larger timesteps. Would it be better if I calculated the maximum and minimum allowed values for acceleration based on the uncertainty and averaged those together to come up with my average acceleration or should I just take the mean of the calculated accelerations? | |
