An Astronaut on the Moon drops a rock straight downward from a height of 1.25 meters. If the acceleration of gravity on the Moon is 1.62 meters per second squared, what is the speed of the rock just before it lands?

V = sqrt(2 a X) when the initial velocity is zero.
a is the acceleration rate
X is the distance fallen
Solve for V
