  1. what do you mean? i've definitely seen it done this way before, and i'm not making it up off the top of my head or anything. i'm almost completely certain that it works.

    look here:trajectory wikipedia

    if you scroll down 4/5 of the way or so, look for equation 10- it's exactly the same thing with different variables.

  2. the position of a projectile divided into x and y components is:

     

    [Math] x=v_{0x} t [/math]

    [math] y=v_{0y} t - \frac{1}{2} g t^2 [/math]

     

    solve for [math]t[/math] and plug in:

     

    [math]y= \frac{v_{0y}}{v_{0x}}x - \frac {1}{2} g (\frac{x}{v_{0x}})^2 [/math]

     

    then, you know that

    [math]\tan \theta_0 = \frac {v_{0y}}{v_{0x}}[/math]

    and the x component of the initial velocity is

    [math] v_{0x} = v_0 \cos \theta_0 [/math]

    plugging those in, you get

     

    [math] y= (\tan \theta_0)x - \frac {g}{2(v_0 \cos \theta_0)^2} x^2[/math]

     

    you can see [math]a[/math] and [math]b[/math] pretty clearly like that i think

     

    hopefully this helps... first time i used latex... maybe it'll get less annoying when i get used to it

  3. People are very possessive' date=' and they don't want to leave their house and all their worldy possessions because they feel that if they lose everything, that they'll have nothing (imagine that) and would rather die. So they figure that they'll take the chance of dying because they feel that if nothing happens, they will have put up a lot of fuss for nothing, and in the time it takes to get out and back, someone could easily break in a steal things. etc. etc.

    ....

     

    Finally, remember that the hurricane missed NO. It hit some poor town (that I can't even think of the name right now) that no one has heard of. That town is completely destroyed (even more so than NO), and yet most of the relief & aid is going to NO, because everyone's heard of it. (also because that town is much smaller than NO, and didn't requre much aid, and right now really just needs rebuilding). But the media hasn't said much at all about where the hurricane hit (that I've seen anyway).

    ....

    I do believe that the govt. has handled the situation quite nicely. You can't be ready for natural disasters everywhere at all times. Given 24 hours notice (even 48 hours) although it seems like a very long time, it really isn't. You're not talking about evacuating a small town of 10,000 (like the one I live in), you're talking aobut more than a million people! Most of whom can't get out on their own. Next, take into account the feeling of "whew" when the hurricane missed NO, and most people around there were thinking the danger had passed. Next day, whoops! The levy broke! We're all doomed, while relief efforts are helping where the hurricane hit (which the media wasn't reporting on btw, they were talking about NO at the time.)

    ok, first of all, people (in my experience) don't stay for hurricanes because they're possesive, they stay because they think they'll be fine and that the storm can't hurt them. my dad was going to stay so that his work wouldn't be interupted... i, along with my family, convinced him to leave once the storm became a cat. 5. my neighbor did stay, and he did ok. people do survive these things, and when they survive, their confidence builds, and they're more likely to stay for the next one. also, in the past, looting during an evacuation (yes, the city has been evacuated many times before) has never been a major issue at all.

     

    also, i assure you that more aid is going to new orleans because it needs more aid, not because more people have heard of it. yes, gulfport and biloxi and the surrounding mississippi gulf coast was hit directly and sustained lots of damage, but there, the water receded and affected the region right on the coast. four fifths of new orleans had water, that's a lot of land, and there's a hell of a lot more people in need of immediate help there than in mississippi.

     

    i got the feeling that because new orleans was only sideswiped by the eye of the storm, the media sorta put the story on the backburner. then the levy broke and suddenly we're the main story again, and then the national government sends in some help. (it did seem like forever to me). the evacuation actually went better than other recent ones. of course not everyone could get out, and coordinating transportation for people who can't afford to get out or don't have the means would be a nightmare to organize because there are so many of them.

     

    that's basically all i have to say. i appreciate anything ya'll donate very much. thanks for the support.

  4. can't copy for some reason, but here's what it says:

     

    looking up jersey.blackcobalt.net

    connecting to 69.50.242.98, port 6667

    sending login information...

    jersey.blackcobalt.net- ***Looking up your hostname...

    jersey.blackcobalt.net- ***Found your hostname (cached)

    timeout connecting to jersey.blackcobalt.net

     

    then it tries again

  5. Well if you can get a 1600 on your SATs and still[/b'] get rejected, then who gets in? Nobel laureates? Sounds like admission is more political than academic.

     

    at the level of M.I.T., a lot seems like it's thrown to chance. i talked to an admissions guy there and he said that MIT couldn't choose the best, they had to choose from among the best.

  6. how do a talent in piano, joining in clubs make you more eminent than others on university admission?

     

    unitversities generally want multitalented, well-roundend students so they can keep or better their reputations. extracurricular stuff is incredibly important to admission. they don't generally want people who study all day and do nothing else- academic perfomance is important- probably the most important thing in admission, but it certainly isn't the only thing.

  7. that's the new orleans arena- it's pretty new- the hornets play (or used to play) there. it's also incredibly ugly- definitely not the same kind of roof- i think the superdome had a white foamish material on it... the arena has a much more metallic roof. and the walkways aren't covered, just cement bridge-paths.

  8. Seems like it. Simple test' date=' plug in 7.999999 or 8.000001, and see what you get ;)

    [/quote']

     

     

    i don't think the 7.9999 thing would work very well in this case... it would take a bit of a leap i think to go from 17885.748 to 6e^8. that's why it helps to know how to do these things manually sometimes.

  9. i've seen some of the smartest, most well rounded people rejected from there... a friend of mine was valedictorian, a professional-level pianist/violinist, 1600 SAT/36 ACT, in every club/service organization imaginable, and he was rejected. the applicant pool to MIT is ridiculous- if you get in, it's like winning the lottery- just about no one is guaranteed entry. there are a lot of other good schools out there that you should look into. good luck though.

  10. i give up on that one, man. i tried messing around with it a bit, but i got very close to nowhere with it. algebra was never my strong point anyway. i guess this post is meaningless, but i'd be really really happy if someone figured this out and posted it because it's been annoying the hell out of me.

  11. it isn't ignorance most of the time... people who live in hurricane prone areas are very used to hurricanes. i'm 18 and i've been through at least 10, maybe 15 or so and i've gotten through fine. people don't realize how strong these things can be because they're used to getting sideswiped or being hit by relatively weak storms. a lot of the people who die are also stuck in the position they're in- tourists with out a flight out or access to rental cars, people who can't afford to leave, people like my aunt and uncle, who can't get very far away because they're in charge of caring for over 50 sick elderly people. don't assume everyone's stupid because of the few that are.

  12. ....And you can't be too young either. I met "the one" at the tender age of 20, and decided to marry her several months later. My friends all say I am too young, and that i should "live my life". But don't buy into that. You are never too young or too old to find love.

     

     

    i hate that "live your life" line- i get it way too much. i just do what makes me happy- which at this point has a lot to do with making a certain other person happy.

  13. ok, irc used to work fine for me, but for the past few weeks it's been giving me trouble regardless of the client. it looks like it connects, then it looks up and finds the hostname, then it times out. i'm not exactly sure what any of this means, but it's not working. any help would be appreciated.

  14. I totally agree on both counts, and do the same thing, reading a good Dean Koontz in a Starbucks while sipping a hot apple cider or a cold vanilla bean, glaring and snarling at almost anyone who came too close to me. One of the reasons it took so long for me to build a meaningful relationship :embarass:

     

     

    yeah, snarling'll do that to ya. haven't been able to get into irc for a while for some reason. it does the whole connecting... logging in... thing, but stops and gives up after a while. that was off topic... eh... i can identify with lots of people on this thread. all i can say is patience can have its rewards if you're open enough. damn you, irc, work!

  15. the water breached a levee in new orleans east- there's a big chunk of land there under 8-10 feet of water. apparently there are bodies floating in the water there and at least 200 people or so waiting for rescue from their roof. just about no one has power and it could be out for a month. no news on when anyone will be able to get back.

     

    personally, i don't know what's happening with my home. all i know is that a building was destroyed less than 5 miles from my house. no idea if there is any flooding, though. my 80-year-old neighbor stayed behind and we can't get in touch with him. your prayers are appreciated.
