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 reach the edge of a 7.5 m waterfall. If the spy's speed is 19 m/s and the officials' speed is 24 m/s, how far apart will the two vessels be when they land below the waterfall?

time to fall 7.5m
7.5=1/2 g t^2 solve for t.
distance apart= relativevelocity*t
= 5m/s * t
