This video shows you how to use conservation of mechanical energy to determine the final velocity of a spent booster rocket before it strikes the surface of the moon.

A real world example from the LCROSS satellite is used in this video.
The Lunar Crater Observation and Sensing Satellite (LCROSS) was a robotic spacecraft operated by NASA.  The mission was conceived as a low-cost means of determining the nature of hydrogen detected at the polar regions of the moon.  It was successful in confirming water in the southern lunar crater Cabeus.
