    1337 speak is a kind of abbreviation used by gamers. Basically, numbers and symbols are used to represent letters...kind of like a deformed alphabet, for example 1337 1-L 3-E 7-T The symbols just have to vaguely look like the letter. 1337 stands for "leet" which is supposed to be short for...

    Thank you so much for all that you've done, you've really been a big help.

    Kinematics (Vectors, fairly easy stuff)

    Yes, thanks, it makes sense now. For number two would I do the same? Since I have an angle this time, I think I need to do something like V1 = (320km/h SIN35, 320km/h COS35) V2 = (75, 0)

    Kinematics (Vectors, fairly easy stuff)

    V1 = (1.2m/s, 0) V2 = (0, 4.6) Well...if I put those in the pythagorean equation, I get a final answer 4.9 and then I put it in tan-1 and I get approximatly 79 degrees...am I on the right track or am I still off? Edit: oh wait, I see, am I supposed to subtract the x-component of V1 with the...

    Kinematics (Vectors, fairly easy stuff)

    I think for the angle I would have to use tan-1(hyp)? (-1 being in the degree mode) right?

    He said h3 10\/35 j00...don't you feel special :biggrin: While I do understand the 1337 speak, it's just too much of a hassle to read, heck, it's annoying in game and it's annoying outside of the game.

    Kinematics (Vectors, fairly easy stuff)

    Can someone please help me out with some of these questions? 1) A scientist runs to the east at 1.2m/s when he suddenly realizes he forgot his chemicals at home. He then dashes at 4.6 m/s [North]. What is the scientists change in velocity? So far I have 4.6 m/s - 1.2 m/s = 3.4, does anyone...

    Lens equation...isn't the lens equation the same except it has a negative for the distance image?

    How can I accurately measure my own intelligence?

    From what I can remember from one of my teachers French class lectures (yes, he taught us this in French class) that IQ tests are fairly meaningless. The number will only show your "smartness" in relation to the person who made it. Also, everyone is smart in their own way, some have a very hard...

    Optics (refracting light) and (mirrors)

    Thank you for all your help with question 1, I'm sorry I didn't state question 2 clearly. The mirror equation I am using is H(image) / H(object) = D(image) / D(object) where H is height and D is distance. With question 2, I know vaguely of what I am supposed to get but I am having a hard time...

    Optics (refracting light) and (mirrors)

    1)For my homework, I received a question, I'm supposed to use Snells law and a protractor. Basically, I have an odd shaped object that forms a messed up sphere. I have an arrow going in at a specific point and I'm given n = 1.0 (for the light ray outside the sphere) and n = 1.2 (for inside...
