Review

Equations 7-1 involve the $\textit{accelerations}$ of the skateboard and you, but we’re interested in the velocities of the skateboard and you after the push-off. To see how to get these, let’s go back to the definition of the acceleration vector in Section 3-5. This definition tells us that
