Answer:
(1) Percent Difference = 2.47%
(2) Percent Error (9.96 m/s²) = 1.63 %
Percent Error (9.72 m/s²) = 0.82 %
(3) Percent Error (Mean) = 0.41 %
Explanation:
(1)
Percent Difference = [(9.96 m/s² - 9.72 m/s²)/(9.72 m/s²)]*100 %
<u>Percent Difference = 2.47%</u>
<u></u>
<u>(2)</u>
Percent Error = (|Measured Value - Original Value|/Original Value)*100%
Therefore,
Percent Error (9.96 m/s²) = (|9.96 m/s² - 9.8 m/s²|/9.8 m/s²)*100%
<u>Percent Error (9.96 m/s²) = 1.63 %</u>
Now,
Percent Error (9.72 m/s²) = (|9.72 m/s² - 9.8 m/s²|/9.8 m/s²)*100%
<u>Percent Error (9.72 m/s²) = 0.82 %</u>
<u></u>
<u>(</u>3<u>)</u>
First we need to find the mean of values:
Mean = (9.96 m/s² + 9.72 m/s²)/2
Mean = 9.84 m/s²
Therefore,
Percent Error (Mean) = (|9.84 m/s² - 9.8 m/s²|/9.8 m/s²)*100%
<u>Percent Error (Mean) = 0.41 %</u>
