energy: joules = kg m^2 / s^2

speed: m/s

energy / speed: kg m/s (units of impulse or momentum)

Bekki is right about it having the same units as momentum. In terms of physical significance, the *kinetic* energy of an object mv^2/2 divided by its speed v is equal to half its momentum mv/2.

Where do you divide energy by linear speed? Such a situation never occurs. Please check the reference once again
