You attach a meter stick to an oak tree, such that the top of the meter stick is 2.67 meters above the ground. Later, an acorn falls from somewhere higher up in the tree. The acorn takes 0.296 seconds to pass the length of the meter stick. Use g = 9.81 m/s2 for the gravitational acceleration. How high h0 above the ground was the acorn before it fell? Assume that the acorn did not run into any branches or h0 = leaves on the way down.
