Physics help please!

You attach a meter stick to an oak tree, such that the top of the meter stick is $$1.87$$ meters above the ground. Later, an acorn falls from somewhere higher up in the tree. If the acorn takes $$0.246$$ seconds to pass the length of the meter stick, how high $$h_0$$ 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? $$h_0=$$
