While exploring the canopy of the rainforest in equatorial South America, Anastasia falls from a branch 51.0 meters high. Exactly 1.6 seconds later Joe falls from the same branch. How high above the ground is Joe when Anastasia splats into the mud below?

Anastasia takes (sqrt. (2h/g) = 3.226 secs. to hit the mud.
Thus Joe has fallen for (3.226 -1.6) = 1.626 secs.
Joe has fallen 1/2 (t^2 x g) = 12.955 metres.
Joe is still (51 - 12.955) = 38.045 metres above the mud.
