How do I get the final velocity from Vf^2 = Vi^2 + 2ad.

Here are my following numbers:
Vi= 0.3048 m/s
Vf= ?
d = 22.86 m
a = 166 m/s^2
t = Not required

Based on the numbers I have would I set it up this way???

Vf^2= 0.3048^2 + 2*(166*22.86)

This process comes out to an impossible number... Please help!

Also on this problem as well - Never-mind I found what I was looking for, I need to square-root at the end of the equation to get the final velocity. Thanks!!!!
