Let me try the old argument again: When you punch, you have the most force initially, and weaken as the punch continues. If a human was able to deliver a string punch without losing force, following through would be the best option. However, since we can't do that, the most efficient way is to...

Well, I was referring to the fact that the distance is measured from the ground, whereas the actual is 2m up. I've recently conducted a lab nearly identical to this, but I can't for the life me remember how. :cry:

Fargoth beat me to the reply, but that is basically it. Also, not only is Linux more powerful than M$, but it comes with with an unlimited number of extensions and upgrades that put commercial software to shame. Ex: http://www.faqs.org/docs/lnag/lnag_benefits.html#benefits

The only problem is, the force of the apple on the post would be an extra reactionary force. Or is the post blocking just the bat?

I guess that when they say "properties", it means a specific element. Since changing the number of protons (typically) changes the element, that doesn't satisfy the question. It still is quite a terrible question, though.

Well, when dealing with large numbers, short of counting the zeros, I personally can't tell what the number is. Math never was my strong point.

The best thing to do - drop M$, get *nix. Everybody wins. I agree VLC Media player is excellent. Plays virtually all formats of media.

But the problem says: It is a force here.

At the risk of sounding like an uneducated fool: Isn't 45° always the most effective angle to use?

Maybe I'm way off, but shouldn't the times be even? Wouldn't the initial force imparted upon the ball change things? On the way up, you have your force being counter-acted by gravity and air resistance. On the way down, you have just gravity vs. air resistance. This is just my logic here.

Well, for part two, I would think that 45° is the most effective angle. Oh - here's your problem, I think - V_0sintheta (too lazy to do the latex) is not 22. 22. That is (probably) the distance from the ground at the putters foot to the final position. The actual distance would be slightly...

I really need this problem, so here goes the underhanded tactic again. Bump... (not that I needed to say that, but, whatever)

What a worthless post. :devil: [The above is a joke. Don't mean to offend anyone] I looked in the archives, and I found a very similar topic. Here is what is said, roughly a summary of the discussion, with general agreement. I like it. I get what I missed now - the W = F/T model assumes a...

Hmm... interesting... So would that mean that the theory if reducing the impact of car crashes is wrong? Or perhaps car crashes deal with only an instantaneous force instead of a continued one. Well, here's the problem. When you punch, you would be applying the same force, but a held-out...

I didn't want to do this, but... BUMP!
