While you cannot physically square your velocity, such as you are traveling at 10 meters per second, and then there's another dimension where you are 100 meters squared per second squared, velocity squared comes up in various physics calculations. Kinetic energy of an object in motion is (1/2)*mass*(velocity squared). This just means that you take the velocity and square the number, and also square the units, so (10 m/s)2 = 100 m2 / s2 for the calculation.

For an object moving at a variable velocity you:calculate the square of the velocityfind its mean valuecalculate its square root.If the velocity is constant then the RMS velocity has the same value.
VRMS = 1/N times square root of [ sum(Vn2) ]
vf=vi+at² simplifying making vi=0, v=at²t²=v/at=√v/atime equals square root of velocity divided by acceleration (or gravity)
Using the Pythagorean theorem, we can determine the actual velocity in the xy plane to be (the square root of 41) m/s along the vector [5,4].
i dont know i thought you guys figured it out
