My lecturer was asked me to prove that V0= Sqrt(Vi2-2Gs)
Few more hours then I have to hand in my answer~ who can help me

I have no idea what your actual question is so how are we supposed to deduce this equation?

hmm, she just want us to prove that v=v something like that.. in the end we have to change to right side v to become sqrt(v^2 - 2gs) as I stated above~ how? lol do we call that derive?

There is no context to this question at all. What do the variables represent?

I wish I can take photo and show you guys the question :/

What is V0? What is Vi? What is G? What is s?

my advice is: the next time you take a class, pay attention, and ask for help before the last minute. You want your teacher to give you credit for doing something you don't even understand, and you want us to help you in your deceit. I won't, and I don't think anyone else should, but I can hardly stop them.

$\displaystyle s = \frac{1}{2} (v_0 + v)t$
$\displaystyle v = v_0 + at$
