The motion with a constant deceleration is described by the relation

s = v_{0} t - \frac{1}{2} a t^{2} .

Consequently, the graph which shows the distance as a function of time is part of a parabola. Find the vertex equation of this parabola, if

v_{0} = 8 m / s

and

a = 4 m / s^{2}

- \frac{1}{2} (s - 8) = (t - 2)^{2}

\frac{1}{2} (s + 4) = (t + 2)^{2}

2 (s + 8) = (t + 2)^{2}

- 2 (s + 4) = (t + 2)^{2}
