Answer:

D. the proper replacement unit for one joule per second

Explanation:

When energy is divided by the time the energy was used we get power

[tex]P=\dfrac{E}{t}\\\Rightarrow P=\dfrac{mv^2}{t}\\\Rightarrow P=\dfrac{kg(\dfrac{m^2}{s^2})}{s}\\\Rightarrow P=kg(\dfrac{m^2}{s^2})}\times \dfrac{1}{s}\\\Rightarrow P=\dfrac{kgm^2}{s^3}[/tex]

[tex]kg\dfrac{m^2}{s^2}=Joule[/tex]

[tex]P=\dfrac{kgm^2}{s^3}[/tex]

So, the answer is D. the proper replacement unit for one joule per second
