Is There an Equation for Velocity?

[GlobalDuty]

Does anyone know if there exists an equation for finding final velocity by just knowing:
1) Time, 2)final and initial position and 3)constant acceleartion?

-g=\frac{v'-v}{t}

works for your questions, and is the definition of an acceleration. More generally, the usual equation taught is:

\overline{v}=\frac{x_f - x_0}{t_f - t_0}=\frac{x}{t}

this gives \overline{v}= \frac{\Delta v}{\Delta t} since \frac{x'-x}{t'-t}.

where x is position, t is time and the lower indices are f which resembles ''final'' and the 0 resembles ''initial''.Using albegra to calculate velocity is given as x=x_0 +vt.
