Question

A football player runs from his own goal line to the opposing team's goal line, returning to his ten-yard line, all in 25.7 s. Calculate his average speed and the magnitude of his average velocity. (Enter your answers in yards/s.)HINT(a)Calculate his average speed. yards/s(b)Calculate the magnitude of his average velocity. yards/s

Answer 1

We will have that in this particular case the average speed and average velocity will be the same, that is:

$\begin{gathered} v=\frac{10yd}{25.7s}\Rightarrow v=\frac{100}{257}yd/s \\ \\ \Rightarrow v\approx0.39yd/s \end{gathered}$

So, the football player's average speed and velocity are both approximately 0.39 yd/s.
