  \begin{exampleblock}{}
    Let $s(t)$ be the position of an object after time $t$.\\
    The object is in the same place at time $t = 2s$ and $t = 10s$.

    What does Rolle's Theorem tell us about the object? 
    \pause\medskip

    It tells that there is a time $c$ between $2s$ and $10s$
    such that the
    \begin{talign}
      s'(t) = 0
    \end{talign}
    that is, the velocity of the object at time $c$ is $0$.
