Question

Using the data provide in the following image could you help with this question If acceleration is supposed to be 9.8 m/s2 [down], determine the percentage error of your value. And State some possible causes of the error in your measured value. What techniques could be used to correct it?

Answer 1

$\begin{gathered} g=9.8m/s^2 \\ y=\frac{gt^2}{2} \\ error\text{ abs =|}Position\text{ calculated-Position}| \\ \text{ \%}error\text{ abs =}\frac{\text{|}Position\text{ calculated-Position}|}{Position\text{ calculated}}\cdot100 \\ \end{gathered}$
