A runner has a speed of 5 m/s and a mass of 130 kg. What is his kineticenergy?O A. 1625 JB. 3250 JC. 875 JD. 325 JSUBMIT

Sagot :

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

[tex]E=\frac{mv^2}{2}[/tex]

Where m is the mass and v is the speed.

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

[tex]\begin{gathered} E=\frac{130\cdot5^2}{2} \\ E=\frac{130\cdot25}{2} \\ E=65\cdot25 \\ E=1625\text{ J} \end{gathered}[/tex]

Therefore the correct option is A.
