\begin{eqComments}
The following question was taken from a demo quiz, published by
\href{http://webwork.math.rochester.edu/} {\textsf{WebWork}}, the
University of Rochester.
\end{eqComments}

\item \PTs{15} In questions~(\ref*{velfirst})--(\ref*{vellast}), a particle moves
along a straight line and its position at time $t$ is given by
$s(t) = 2t^3 - 15 t^2 + 24 t$, where $s$ is measured in feet and $t$ in
seconds.

    \begin{questions}

    \item\PTs*{3}\QT{velocity}\label{velfirst} Find the velocity (in
    ft/sec) of the particle at time $t=0$:\\[1ex]
    $
        v = \RespBoxMath{24}*{1}{.0001}24\CorrAnsButton{24}
    $
    \begin{solution}
    We have $v(t) = s'(t) = 6t^2 - 30 t + 24 = 6 ( t^2 - 5t + 4 )$ and so
    $v(0) = 6(4) = \boxed{24}$.
    \end{solution}

    \item The particle stops moving (i.e.\ is in a rest) twice, once
    when $t=A$ and again when $t=B$ where $A < B$. Then\dots\smallskip

    \begin{questions}
    \begin{multicols}{2}
        \item $\PTs*{2}\QT{velocity}A= \RespBox[\rectW{.5in}]{1}*{1}{.0001}24\CorrAnsButton{1}$
            \begin{solution}
            From the solution to \hyperref[velfirst]{(\ref*{velfirst})}, we have
            \begin{equation*}
                v(t) = s'(t) = 6 ( t^2 - 5t + 4 ) = 6 (t-1)(t-4)
            \end{equation*}
            It is clear that $\boxed{A = 1}$ and $B=4$.
            \end{solution}
        \item $\PTs*{3}B=\RespBox[\rectW{.5in}]{4}*{1}{.0001}24\CorrAnsButton{4}$
            \begin{solution}
            From the solution to \hyperref[velfirst]{(\ref*{velfirst})}, we have
            \begin{equation*}
                v(t) = s'(t) = 6 ( t^2 - 5t + 4 ) = 6 (t-1)(t-4)
            \end{equation*}
            It is clear that $A = 1$ and $\boxed{B=4}$.
            \end{solution}
    \end{multicols}
    \end{questions}
    \item\PTs*{2}\QT{velocity}\QT{position} What is the position of the particle at time $10$?\\[1ex]
    $s = \RespBox{740}*{1}{.0001}24\CorrAnsButton{740}$
    \begin{solution}
    We have
    \begin{align*}
        s(t) &=   2t^3 - 15 t^2 + 24 t = t ( t^2 - 15 t + 24) \\
        s(10) &= 10 ( 100 - 150 + 24 ) = 10 ( 74 ) = \boxed{ 740 }
    \end{align*}
    \end{solution}

    \item\PTs*{5}\QT{distance}\label{vellast} Finally, what is the \textbf{total} distance
    the particle travels between time $0$ and time $10$?\\[1ex]
    $
        \text{distance} = \RespBox{794}{1}{.0001}24\CorrAnsButton{794}
    $
