A free fal is a body that is under the Influence of gravity only where h the distance of tall in meters, t is time in seconds, and g is acceieration due to gravity. If we can messure the distance of fall for a give time, we can use this equation to determine the acceleration due to gravity) g- measure te eloation due togravity here in Odessa, a physics student dropped a steel ball trom nve dnewt hegts and recorded the corresponding time of tal in table below, calculate g using the above formula and ll the table and answer the question below 0.1 0.135 10.97 02 02 10 04 0.28 1020 0.6 0.36 9.26 0.8 0.4 10 A Calculate the average g valuer Rne8.22 .Caculate the standard deviation of g: (h-i(gj.|2.17 C.

Given the accepted (enown g value to be g 9.80what is the percent difference in g measurement: percent difference- Note: You can eam partial creait on this problem MacBook AiExplanation / Answer
A] gave = [10.97+10+10.20+9.26+10]/5 = 10.086
B] standard deviation = sqrt[((10.086-10.97)^2+(10.086-10)^2+(10.086-10.2)^2+(10.086-9.26)^2+(10.086-10)^2)/(5-1)]
= 0.6106
c] uncertainty = standard deviation/ sqrtN = 0.6106/sqrt 5 = 0.273
d] percent variability = 0.6106*100/10.086 = 6.054%
e] percent difference = [10.086-9.8]*100/9.8 = 2.918 %
