To solve this equation for v, we need to move anything that isn't v to the other side of the equation.

`F={mv^2}/r`   multiply by r

`rF=mv^2`   divide by m

`{rF}/m=v^2`     take sqrt of both sides

`sqrt{{rF}/m}=v`

The solution of the equation for v is `v=sqrt{{rF}/m}` .

F=mv^2/r

F*r/m=v^2

v=sqrrt(F*r/m)
