Here's how to use it:

Menu one:

YOU NEED (you have other two, and need one of below)
1. Height Dropped (what height at which object was dropped)
2. Time till H (The time it takes to reach the given height)
3. Height (What height is it if dropped at given height for given             seconds)

It computes and gives you the answer.

Easy enough?
