1) Of COURSE a single kart can push another but NOT if it’s only AS quick or SLOWER. The example you give is NOT what you said Loading IS! You claimed it to be a ‘train’ of karts pushing a leading kart. However, that has ZERO bearing on whether a following kart, which started accelerating earlier (as YOU claimed), can have ANYTHING other than an instantaneous effect on a leading kart. You CANNOT claim that if your definition of loading was accurate! Your silly claim was that a SLOWER kart can push (load) a leading kart IF it started accelerating earlier. That’s blatantly TRIPE! It can hit it ONCE and, after it has accelerated the lead kart (and slowed itself) a SLOWER kart can NOT ‘load’ a faster kart..... which is what YOU claimed in trying to escape the point I made. David, you should know by now; I don’t fall for these attempts to evade!
2) More tripe! A single kart and a fully ladened locomotive, if they have identical acceleration, MUST have identical effects on the lead kart ONCE the INITIAL impact has finished. Unless, of course, the lead kart is SLOWING (braking) (for example) for a corner! Again, this is about YOUR definition of loading! Yes: a locomotive would deliver a BIGGER single impact than a kart BUT.... assuming the identical acceleration rate, once it ‘hit’ the kart in front, then the continued acceleration effects are OVER! By definition, if they are accelerating at the same rate, once the rear vehicle has speeded up the lead vehicle, they remain in EXACTLY the same relative positions with ZERO CONTINUED force being applied between them! And that was EXACTLY the point we were discussing! Stop trying to evade: it won’t work!
3) Ner, ner, ner..... yes you have! Or you have forgotten your original point!
