You don't even know what a transformation is or what it does,
you cretin. It looks like this:
 http://mathworld.wolfram.com/GalileanTransformation.html

except that Weisstein has omitted velocities u and w in the
y and z directions.


Of course cretins like Einstein and Poe can't handle moving
sideways and up simultaneously. Never step sideways on
an escalator, Poe, you'll be lost in spacetime and dream up
impossible shit like "transverse mass" and "transverse Doppler
shift".
As  I said, you wouldn't know a Galilean transform if it bit you
in the arse, Poe.

Your homework assignment:
Place u, the velocity in the y-direction, in the matrix shown by
Weisstein.
