If we assume that the velocity data can be fitted by the linear equation: Ut) = v, + at
we can determine the initial velocity U,
and the acceleration a of the person.
Use your Excel Template or least squares fitting table from the previous lecture to answer the following questions. Carry at least
two extra decimal places through all statistical calculations, and round appropriately when expressing the final results.
