IS THIS A REACTIONLESS DRIVE OR A PERPETUAL MOTION MACHINE?

George,

I see you insist with repeated ad-hominem. You won't stay long here with your insults, you little prick.

Tell me this: your character is abject, your education is poor, your western culture is almost non-existent and your inclination is clearly toward lying and cheating yet your English is pretty good. Add a high ego and no manners whatsoever. You must come from a former imperial colony, aren't you?

Anyway, I promise you: any time I'll have a spare minute, I'll sign in to smack in your face, moron!

tinu,
All members of this forum already see clearly that you are mad and dangerous. There is no doubt about this. How to have a dialogue with a mad person?
(I would like to appologise to all other members of this forum for my inappropriate words above. But there is no other way for communication with such people like tinu.)

 George,

Haven't I just told you I'll not allow any more impunities?
Is it I was not clear enough or you're really retard?!
Wait for my reply. It will come shortly, as soon as I'll make some time to waste on you.

... we can conclude again that:
a) the law of conservation of linear momentum is not correct;

This assertion is plain stupid. Linear momentum is always conserved. There is no exception.

...we can conclude again that:
b) the law of conservation of mechanical energy is not correct;

This assertion is plain stupid. In a closed system where there are no dissipative forces (as per your assumptions),  mechanical energy is always conserved. There is no exception.
 

...we can conclude again that:
c) both the law of conservation of linear momentum and the law of conservation of mechanical energy are not correct simultaneously.

This assertion is DOUBLE stupid. Both mechanical energy and linear momentum are always conserved. There is no exception.

Let us stress upon the fact that IN GENERAL both the law of conservation of mechanical energy and the law of conservation of linear momentum are absolutely true and correct. There is no doubt about this. But any rule/law has its exceptions and there is nothing special, disturbing and tragic in this fact.

This assertion is the most stupid sample one can read. Laws in physics have no exceptions! A single exception, if identified, would completely invalidate the law!

So George, why don't you go educate yourself a little more before coming here to insult people? If you need links and free books for your education, I can help.
Or, if you prefer, focus you attention to other kind of rules (traffic maybe) where, of course, there can be exceptions.

Please come back only when you're sufficiently enlightened and meanwhile refrain yourself from posting absurdities!

tinu,
1) If you lived at the time of the three musketeers in France, then you should kill tens of people! (I am joking, Professor No-man -- please don't be angry again!) 
2) Here is an abstract from our post from May 16, 2019, 09:35:12 AM. "It is evident that we can always choose a suitable combination of (a) magnitude of force of friction, (b) length of segments s and (c) number and shape of zigzags, for which Fc = F'c, Fc > 0, F'c > 0, d = d', d > 0 and d' > 0." Any objections against this last claim?
