I am a busy monkey !  However , you can view the basic numbers in "Can we feel gravity from objects at different velocities ?" .

The numbers in that thread do not demonstrate a violation of conservation of momentum.

When I have time to burn , I will demonstrate the difference between %2 and %55 .

To whom, and why?

[Professor Mega-Mind (OP)]

Apparently , inquiring minds need to know .

Why do you consider it "apparent"?
Nobody has indicated that they don't know.

Kinetic energy being turned into heat doesn't violate conservation of momentum. If it did, we would have known a very long time ago.

[Professor Mega-Mind (OP)]

Sandbag type collision against Massive-Wall yields ~%45 friction heat , ~%55 inertia transfer to wall. Kinetic energy breakdown for EC :
~%2 transfer to wall , ~%98 retained by ball .
In other words , sandbag pushes hard , pinball bounces back with no effect .

Which also means that the wall pushes hard back on the sandbag while it doesn't push as hard on the pinball. Conservation of momentum is not violated.

Ask No-Ether if she's ever seen a sandbag bounce back off of a wall!
Aaahahahaha...!

Why can't you spell Noether?
Anyway, as I said,

If you don't have time to make sense, don't post.

Incidentally, you might want to try standing on a skateboard and throwing a big bag of sand at a wall.

[Professor Mega-Mind (OP)]

If I stand on a SB in between two walls , and simultaneously a 20lb sandbag right , and a 20lb steel ball left , I ain't moving !  However , the sandbag is going to flop to the ground , while the steel ball will bounce back and thump me !  Which one could push something ?  Come on now , make sense , Mister Manager/Owner !

Well, it seems you are determined to miss the point, but let's try again.

What happens if you stand on a skateboard and throw a heavy sandbag  (say forwards, just to clarify things)?

Why is it different if you stand on the ground
Given that momentum is actually conserved in both cases, what happens in the skateboard-less case?

Clearly the momentum of the bag, while it is in flight, has to be balanced by an opposing momentum, so what else moves?

[Professor Mega-Mind (OP)]

Dude-man , I'm way ahead of this .  Obvi either the man OR the Earth .  My example has counter-throw (opposing force) , which prevents that .  Take my last example , modify it so that the steel ball misses me , and then splats on a sand panel mounted near where the sandbag went splat .  Two strong splats on one wall , one weak ding on the other .  Which wall got shoved hard ? 
Remember , unequal shove equals Reactionless Drive .

With my design , the thrower does not move whether he's on a skate-board or not .  The simultaneous throws oppose each other , negating any net force .  The momentum of the bag is balanced by the momentum of the ball .
It's a tightrope , bubbatugs !

And I pointed out in your other, spurious, thread why this doesn't work
