2) Based on your best-fit analysis of the free-falling ball, estimate the acceleration (g) due to gravity. How does your experimental estimation of g compare to the known value? ackerProgram = 0.020 + 4 m/s2 ivity = 9.8m/s2 7 y =yo + Vot - 1/2gt2 -> (9.8m/s2) x (1/2) = 4.9m/s2 r resistance and friction were considered to be negligible in this experiment, which may have I to the differing values of the acceleration. Given the small mass of a ping pong ball, it is ely that air resistance has a significant effect on its fall. Not accounting for resistance/friction a likely explanation for the large variability between the two accelerations
