    has an acceleration vs. distance profile as shown. (Note this is not
    acceleration vs. time). Assuming it starts from rest and acceleration units of
    in/s^2 with distance units of inches, determine the velocity (in/s) of the boat
    when the acceleration reaches maximum (s=3in) and when the acceleration is
    again zero. Ignore the small segment on the graph where the acceleration
    crosses to negative.</span></p>
