Question

F=mv2r ; for v

v=±

Answer 1

Is it
\[F=\frac{mv^2}{r}\]

Answer 2

yes

Answer 3

\[\left( \begin{array}{c} \text{Divide both sides by }\frac{ m }{r} \\ v^2=\frac{F r}{m} \\ \end{array} \right)\]
\[\text{Take the \square \root of both sides}\]
\[v= \pm \sqrt{\frac{F r}{m}}\]

Answer 4

ohhhhh ok yea thats what i got, but it wasnt taking my answer so y typed in rf instead and i got it right thank u!:)
