3. The attempt at a solution

Suppose I had an expression, for the sake of this post

[tex]\frac{Ec^2}{mv}[/tex]

we know that [tex]c^2 = \frac{E}{m}[/tex] so can the above expression be substituted as

[tex]c^2 \frac{c^2}{v}[/tex]

Yes, yes, I know this result is very uninteresting, I was just making a quick example. Thank you!
