Consider a large cylindrical tank of water that has a hole in the side. Water is
shooting out the hole, and hits the ground a distance of n3
from the base of the tank. The hole
is located a distance of n1 from the surface of the water.
The height of the tank is n2. What is n3, the distance
from the tank to where the water lands? Note that n1, n2 and
n3 all have have the same units of length.
