Using the ``Turntable Hockey'' Mathematica worksheet on the course website, you will explore how rotation impacts 2-dimensional motion.
\begin{enumerate}
\item[]
\begin{itemize}
\item Make sure you understand the default pictures.
\item Try the canned examples at the end.
\item Try your own initial configurations.  
\begin{itemize}
\item Compare initial velocities pointing in with those pointing out.  
\item Compare initial velocities in the direction of rotation with those opposite the direction of rotation.  
\item Compare different values of $\Omega$.
\end{itemize}
\item Try to produce a boomerang, a configuration which returns to its
initial position as seen by the rotating observer.
\item Try to produce a right angle, a configuration which makes a sudden
turn of $90^\circ$ as seen by the rotating observer.
\end{itemize}

\bigskip
\item  Print out any single picture of a situation different from the preconfigured examples. 
Each group member should construct a different picture. \\
\emph{\textbf{Note:} It is difficult to print/save/export an animation.  Instead, click on the picture and choose ``Print Selection'' from the File menu.}
\vfill

\item Indicate the values for all parameters used on the printout.
\vfill

\item Describe briefly in words how both the rotating and non-rotating observers would describe the motion.

\end{enumerate}
