A spy in a speed boat is being chased down a river by government officials in a faster craft. just as the officials' boat pulls up next to the spy's boat both boats reach the edge of a 5.0meter waterfall. If the spies speed is 15m/s and the officials' speed is 26 m/s, how far apart will the two vessels be when they land below the waterfall?

Goodness.
time to fall 5 meters:
h=1/2 g t^2 solve for t on the waterfall drop.
distanceapart=(2615)t
