The motion with a constant deceleration is described by the relation
\[
s = v_{0}t -\frac{1}
{2}at^{2}.
\]
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
\(v_{0} = 8\, \mathrm{m}/\mathrm{s}\) and
\(a = 4\, \mathrm{m}/\mathrm{s}^{2}\).
\(-\frac{1}
{2}(s - 8) = (t - 2)^{2}\)
\(\frac{1}
{2}(s + 4) = (t + 2)^{2}\)
\(2(s + 8) = (t + 2)^{2}\)
\(- 2(s + 4) = (t + 2)^{2}\)
