Im fucking lost when it comes to re-arrangeing these equations for uniform acceleration (grade 11, physics), could someone help me?

I don't have anyone else to ask, dads not home for a few days, don't have a mom to ask, and my old tutor moved away...

You could start by posting the equations...

Tangent of V/T = amount of Acceleration

I haven't learned it, but couldn't you just subtract Vi^2 and then divide by 2deltaD?  That's the math part of me talking.

Vf^2 = Vi^2 + 2                    Aav                      deltaD

an what i was attempting to do was divide Aav out and i would end up with something like this:

but then i don't know what to do from there...

wat you doing

take

(Vf^2-Vi^2)=2AavD

(Vf^2-Vi^2)=(2D)Aav

(Vf^2-Vi^2)/(2D)=[Aav(2D)]/(2D)

(Vf^2-Vi^2)/(2D)=Aav

If I'm not mistaken, wouldn't you not be allowed to do that?  Becuase you didn't divide the Vi^2 on the other side by Aav.

Or maybe I just don't understand physics equations because all I've done in the past 2.5 weeks of physics class is build a rubber band car to teach us about physics and then today we timed our teacher on his motorcycle in the parking lot to try to learn about acceleration I think.

If it follows all the rules of algebra, that would be right.  You don't need to know physics to do it.

That's what I said in the beginning and I'm taking my first class of physics in the 11th grade.

Looks good to me! Combining terms like that is a really useful trick that you'll see a lot in physics.

I'd say that's right as well.

Go here http://www.khanacademy.org/ and watch some of the math and physics videos. I guarentee you will understand it. The way he teaches isn't like any teacher/professor, you actually understand it. It is awesome.
