A football player runs from his own goal line to the opposing teams goal line returning to his tenyard line all in 257 s Calculate his average speed and the mag class=

Respuesta :

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

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

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