V=v0 + 2at ? or V=v0 + at ?

[r3dxP]

which one is correct?

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

 

[Pengwuino]

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

$$v^{2}=v_{0}^{2}+2 a x$$

also valid for constant acceleration along the Ox axis.
