<0> nite
<1> hey guys. is there any possible way to find a vector sum of zero if you have two different vector lengths?
<1> vector lengths are always positive, so it doesn't make much sense
<1> it's a homework question
<1> lol
<2> I'll walk you through it, but you need a paper clip, a rubber band and some sticky-back plastic.
<3> "A car with a m*** of 800 kg moves at 15 m/s. What braking force is needed to bring the care to a halt in 10 s?" I am unsure of where to start exactly, because I don't know what equation I would use to solve this, any ideas?
<4> Breaking force would be a good start; is that just some applied friction?
<3> Yes
<3> So I need to find the force of which the car is moving, and then how to apply the same amount of force in 10s?
<4> That sounds reasonable.
<4> Sorry I don't have an equation off the top of my head,
<4> I work more in terms of sentences and explanation more than mathematics strangely enough (!)
<3> So I'm fairly sure I need to multiply 800*15, hmm, but for some reason it doesn't seem to be correct
<5> I found some feasible to make pcb dimensions to make a negative index of refraction metamaterial in the 13 to 15 Ghz range. It's neat in a useless way. http://nervousenergy.net/_/?q=node/227

<3> But then it would have to account for the fact that it takes 10 seconds and you apply that much force every second so 800*15/10
<7> "Good-bye, sun," she said. The tiny red arc dipped and vanished, and for the first time in her life she saw, in the last second of refracted light, a brief flash of green. She had been told about that in high school, and the teacher had said it was very rare (and hadn't bothered to explain what caused it) and now she grinned with pleasure. She had actually seen it.
<7> anyone heard of this phenomenon?
<3> I have heard of it
<3> I saw a picture of it actually
<8> ive not seen it, but looked many times
<3> On Cliff Pickover's reality carnival website
<8> i think it exsists however
<3> If I recall they had an explanation for it, but I don't know if it was a definite explanation
<7> ah, it's called "green flash" apparantly
<8> faynmann covers it in his lectures
<8> feynmann*
<4> Feynman.
<4> Here's an interesting subject:
<4> Was Feynman a synesthete? He describes something in one of his books (Surely your Joking, or another one of them)
<4> It would make sense that he never mention it; he was the "Great Explainer" and would have compromised the public's trust in his ability to explain things to people without those brain abilities (so to speak)
<4> just an interesting subject
<7> there was a k5 discussion on the matter

<9> It's Mr. Hyde time, gentlemen.
<9> so what happened to discussing green lights?
<9> nutty
<10> PHYSICSMASTAAA, you are a of
<9> pardon?
<9> Pick on someone your own size, jer

<8> please knock it off with the colors already

<9> what a cockmaster
<10> ahahaha
<9> I'm watching a really funny show right now..its about lifeguards in San Diego
<9> and the main case at the moment was a couple having *** in the beach restrooms
<3> "A railroad diesel engine weighs four times as much as a freight car. If the diesel engine coasts at 16 km/h into a freight car that is at rest, how fast do the two coast after they couple?" I am absent of an equation to solve this as well, ideas?
<9> hmm
<4> Use elastic ("they stick together") collision equations.
<4> (Do a search!)
<3> okay
<10> okay

<9> YOU DISSING THE WIKI!?
<4> YES MASTAAAAAAAAAAAAAAa
<9> OH IT'S ON!
<10> oh yeah?
<9> YEAH
<10> not you
<9> aw
<9> you gonna take that kanzure?
<4> For the moment, yes,
<10> For the moment, yes,
<4> I deserve it
<11> DanF_DrC, sacarasc, ro some other op, could you please get rid of jer`?
<10> I deserve it
<4> due to the paper I'm writing on feminism (ugh!)

<3> If the time of impact in a collision is extended by eight times, by what factor does the force of impact change? It seemed ot me it would be 8 at first, but then i figured it would be 8 times slower than it was before hence by a factor of 64, but neither are correct. I do not know how to figure out by what factor the impact time changes the impact change :-/
<10> my number
<10> my number guessing scri[pt doesn't work
<10> it was
<9> what was the number jerpants?
<10> 15
<9> !spin
<10> Bottle is turning for you PHYSICSMASTAAA .... And the person you want is .... navaburo_ !!
<10> !Spin
<9> <3 you navaburo
<10> TRY IT

<10> Bottle is turning for you harkeyahh_ .... And the person you want is .... blake6489_ !!
<3> figures
<9> I knew it all along.
<10> ZOMG GROSS
<9> that ****'s gonna hurt, corpse
<9> geez
<10> (harkeyahh_): dude-kisser!
<3> comes as no suprise
<11> Ugh, are there no ops around?
<3> surprise*
<10> I AM THE OP BITCH!
<12> Apparently not.
<11> Very convincing.
<3> how irresponsible of the ops
<3> we should all cyber
<13> But no - no - I don't think you're understanding the point here. It doesn't matter as to what extent or velocity you accelerated at. You...you just aren't grasping the entire picture. ****. Look - let me try to explain this one more time....
<3> and leave a big mess for them to clean up
<10> touch my balls!
<3> graphix who are you speaking to?
<10> .nick jer|away
<9> !roll
<10> The dices are turning for you PHYSICSMASTAAA !! The possibilities to win are 10%!!
<10> You lost because you brought 73
<9> dammit
<13> You have 8 congruence units of linear-ness, you can't evenly distribute them amongst a channel off odd parity. It is just not ****ing possible. Would you conduct an open proton inclusion without the proper clavintonium in check? I don't think you would.

<10> Congratulations!! You brought 7 !! You have won.
<3> I always win
