Physics (need help) due tomorrow morning

    1. I have to show how i go from this: x=1/2 at2 + V0t + x0
    to this: V2 = V02 + 2a(x-x0)



    2. Algebraic Manipulation



    3. I get here and get stumped: 2(x-x0) = at2 + V0t
    1. The problem statement, all variables and given/known data



    2. Relevant equations



    3. The attempt at a solution

    The equation you're starting with does not have v in it, so you can't possibly get the equation you want from it alone. You need another equation as well, one that involves v. After you've remembered what it is, use it to solve for t, then plug the result into your first equation.
