Yes, it does - theoretically
The ping time is the sum of
In modern copper wire the signal speed is about 85% of the speed of the light in vacuum, so you get something like 26cm per ns. If you compare the shortest possible cable to the longest possible cable in the CAT5/CAT6 ethernet domain you will find the difference is ca. 400ns - which is typically much less than any of the other time slices.
You are talking about a CAT5 cable? There is however a maximum allowed length of a CAT5 cable, about 100 meters if I recall rightly.
But since signals propagate in about a billionth of a second per meter, no it would not make any measurable difference to you, I'd imagine.
I think that if it made any difference, it would be due to heavy interference of some kind causing packet loss by introducing noise into the signal, and that being exacerbated by the length. But that's something you'd solve with more shielding.
