You attach a meter stick to an oak tree, such that the top of the meter stick is 2.27 meters above the ground. Later, an acorn falls
from somewhere higher up in the tree. If the acorn takes 0.126 seconds to pass the length of the meter stick, how high $h_o$ above
the ground was the acorn before it fell, assuming that the acorn did not run into any branches or leaves on the way down?
