Question

A 55kg football player runs a 100.0 meter race in 11.45 seconds. Find the average speed of the football player.

Answer 1

The average speed of player can be given as,

$v=\frac{d}{t}$

Plug in the known values,

$\begin{gathered} v=\frac{100.0\text{ m}}{11.45\text{ s}} \\ \approx8.73\text{ s} \end{gathered}$

Therefore, the average speed of player is 8.73 m/s.
