\begin{document}% Abstract should be put before `\maketitle'\begin{abstract}We determine the sweet spot on a baseball bat. We capture the essentialphysics of the ball-bat impact by taking the ball to be a lossy spring and thebat to be an Euler-Bernoulli beam. To impart some intuition about the model,we begin by presenting a rigid-body model. Next, we use our full modelto reconcile various correct and incorrect claims about the sweet spot foundin the literature. Finally, we discuss the sweet spot and the performances ofcorked and aluminum bats, with a particular emphasis on hoop modes.\begin{keywords}dream; cometrue\end{keywords}\end{abstract}\maketitle\pagestyle{empty}% Generate the Table of Contents, if it's needed.\tableofcontents\newpage
