Answer:

u = the square root of ([tex]v^{2} - 2 as[/tex])

Step-by-step explanation:

I could not figure out how to get [tex]v^{2} - 2as[/tex] under the square root symbol so I typed it out in the answer.  To solve for u, we subtract 2as from both sudes and then take the square root of both sides.  Hope this helps!
