Well, this has been discussed. But as I keep pointing out, the forces literally do not enter the equations for what happens after inelastic collisions (or elastic ones, for that matter). As I have done on many previous occassions, I recommend you Google "inelastic collisions" or go straight to http://en.wikipedia.org/wiki/Inelastic_collision and note the complete absence of any force term or even any terms with the units of force in any of the discussion or solutions. The concept of "force" is as relevant to solving the equations of motion for collisions as is the colour the floors were painted - ie completely irrelevant. That is why the Wikipedia page (and Physics 1 textbooks) don't even mention "force" as something that enters the equations. > He keeps trying to divert his answer to the time period that it was > falling, but before the collision, but, as we've both pointed out, the > statement refers to the time DURING THE COLLISION. > Actually, the exact word they use is "falling", but that doesn't matter; as I said their statement is absolutely correct. > Hell, he's the one who also came up with the analogy of a blob of goo > being thrown at, and hitting, a wall, and yet, he's never been able to > tell us whether or not he thinks that this collision resulted in a force > being applied to the wall.

You know this because you responded many times to that argument. Moreover, the statement itself, when taken as a whole, and not parsed as you keep doing so as to obfuscate the issue, is clearly indicating that the "N" to which they refer is a reaction to "mg" (i.e., the weight of the upper block). Not the result of resisting the momentum of the upper block, but of the weight "(mg)" of the upper block. And the proof that this is so is contained in what followed in that report. And before you go there, what followed in that report had been posted here very many times by your KOOK brethren, and so you cannot claim that you didn't know the context unless you lie, which, of course, you will. And you can keep claiming that I've never told you what other force was at play during that collision, but that's just another lie on your part. I've said it all along, and I'll say it now. The force ignored by that statement was F=(d/dt)mv. And BTW, as to your response about your other mistake? "All I [you] did" was entirely incorrect as it pertained to the question. What you did was analogous to someone asking you what color the sky is, and you answering that the ocean is deep. It's a valid comment, but it's wrong as it pertains to the question. The question at hand was how much resistance the support structure provided to the fall of the upper block, and your approach was to assume zero as a premise to your answer. Notwithstanding the fact that your approach was overly simplistic anyway, it was nonsense as an answer to the question at hand. >> Look, I'm tired of all of your shaking and baking and every other >> kind of obfuscation you're tried to throw out there just to avoid >> admitting your mistakes.

There is no IF, KOOK! It's right there in the statement. And during the collision, the force normal to the upper block (N) isn't the mg of the falling block, it's the (d/dt)mv of the falling block. The statement is therefore wrong, and anyone who says it's right is also wrong. That's you, KOOK! >> All the rest of your bullshit is just a cover for the fact that >> you thought that statement was made by the NIST, and so you >> defended it, no matter what it said, and now you can't admit it. >> >> > > I defended it because its true. > > Simple as that. Yes, you're a very simplistic thinker. That's why you tried to answer the question of whether or not there was any resistance to the falling block by assuming there was none from the outset. LOL!
