F=f (1-v/s) change the subject of the formula into v

Artyom0805 [142]

Changing the subject of the formula into v means expressing v in terms of the other given variables. So given the original equation, as shown below, we can rearrange it so that we have v isolated on one side.

$F = f(1 - \frac{v}{s})$
$\frac{F}{f} = 1 - \frac{v}{s}$
$\frac{v}{s} = 1 - \frac{F}{f}$

To isolate v, we can just multiply s to both sides and come up with the final equation below.

$v = s(1 - \frac{F}{f})$

Thus, we have v = s(1 - F/f) with v as the subject of the formula.

Answer: v = s(1 - F/f)
