In order to calculate the kinetic energy of the runner, we can use the following formula:


E=(mv^2)/(2)

Where m is the mass and v is the speed.

So, using m = 130 and v = 5, we have:


\begin{gathered} E=(130\cdot5^2)/(2) \\ E=(130\cdot25)/(2) \\ E=65\cdot25 \\ E=1625\text{ J} \end{gathered}

Therefore the correct option is A.
