    For the record, you're assuming that the brick ends up in sand at the bottom of the slope, coming to an abrupt stand still.
    The corresponding graphs then look like:
    \begin{tikzpicture}[font=\LARGE]
    \draw[thick, gray, ->] (0,0) -- (9,0) node[right] {$t$};
    \draw[thick, gray, ->] (0,-6) -- (0,4.5);
    \draw[ultra thick, red] (0,2) node[left] {$a$} -- (5,2) -- (5,-6) -- (6,-6) -- (6,0) -- (8,0);
    \draw[ultra thick, blue] (0,0) -- (5,4) -- (6,0) -- (8,0) node[above] {$v$};
    \draw[ultra thick, olive] (0,0) parabola (5,3) parabola bend (6,3.6) (6,3.6) -- (8,3.6) node[right] {$d$};
    \end{tikzpicture}
    (Just had to make the TikZ drawing. )
