Question

A=v^2/r Solve the formula for r

Answer 1

Answer:

$\Large \boxed{r =\frac{v^2 }{a}}$

Step-by-step explanation:

$\displaystyle a=\frac{v^2 }{r}$

We need to rearrange and solve the formula for $r$.

Multiply both sides of the equation by $r$.

$\displaystyle a \times r=\frac{v^2 }{r} \times r$

Simplify the equation.

$ar=v^2$

Divide both sides of the equation by $a$.

$\displaystyle \frac{ar}{a} =\frac{v^2 }{a}$

Simplify the equation.

$\displaystyle r =\frac{v^2 }{a}$
