twice the kinetic energy
1Kinetic energy — The kinetic energy of an object is the extra energy which it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its current velocity . Having gained this energy during its acceleration …

4Sailing faster than the wind — Devices that are powered by sails (such as sailboats, iceboats and sand yachts) can sail (that is, advance over the surface) faster than the wind.[1] Such devices cannot do this when sailing dead downwind using simple square sails that are set… …
5Characteristic energy — In astrodynamics a characteristic energy ( ), a form of specific energy, is a measure of the energy required for an interplanetary mission that requires attaining an excess orbital velocity over an escape velocity required for additional orbital… …
