Question

2. A common formula in physics is shown below. my2 FE a) Solve for m in terms of F, v, and r. b) Solve for v in terms of F, m, and r.

Answer 1

1)

a) Solving for m, is isolating the m variable on the left side like this

$\begin{gathered} F=\frac{mv^2}{r}\text{ } \\ mv^2=Fr\text{ } \\ m=\frac{Fr}{v^2} \\ \end{gathered}$

We need to Cross multiply like a ratio, and then divide both sides by v²

Now we can solve for m.

b) Similarly, let's now solve for v, in terms of F, m and r
