Homework Help: V=v0 + 2at ? or V=v0 + at ?

    which one is correct?

    V=v0 + 2at ? or V=v0 + at ?
    where v0 is initial and a is acceleration and t is time.

    V=v0 +at

    The acceleration part should be common sense. Acceleration * time = velocity.

    You're mixing the simple time integration of constant acceleration with Galilei's formula

    [tex] v^{2}=v_{0}^{2}+2 a x [/tex]

    also valid for constant acceleration along the Ox axis.
