The motion with a constant acceleration is described by the relation
\(s = \frac{1}
{2}at^{2}\).
Consequently, the graph which shows the distance as a function of
time is part of a parabola. Find the directrix of this parabola, if
\(a = 4\, \mathrm{m}/\mathrm{s}^{2}\).
\(s = -\frac{1}
{8}\)
\(s = -1\)
\(s = \frac{1}
{8}\)
\(s = 1\)
