Answer 1

`a = \frac{ {v}^(2) - {r}^(2) }{2x}`

Step-by-step explanation:

`{v}^(2) = {r}^(2) +2 ax`

To make a the subject first move r² to the other side of the equation

That's

`2ax = {v}^(2) - {r}^(2)`

Divide both sides by 2x to make a stand alone

That's

`(2ax)/(2x) = \frac{ {v}^(2) - {r}^(2) }{2x}`

We have the final answer as

`a = \frac{ {v}^(2) - {r}^(2) }{2x}`

Hope this helps you
