V f2 =V i2+2ad SOLVE FOR Vi

2=squared

Try reposting your equation using mimetextutorial.html.

Your equation is ambiguous.

If I understood well,

$Vf^2 =Vi^2+2ad$

Then, subtract 2ad from both sides;

$Vf^2 -2ad=Vi^2$

And put in square root on both sides to eliminate the squared.

$\sqrt{Vf^2 -2ad}=Vi$

I think the OP meant to write the formula for velocity given acceleration and distance, where $V_f$ is final velocity and $V_i$ is initial velocity:

$<br /> {V_f } ^2 = 2ad + {V_i} ^2<br />$

Rearrange and you get:

$<br /> V_i = \sqrt{{V_f} ^2 -2ad}<br />$
