I need some serious help.

Well, its been a long time since I posted on here, but I figured, I need help, why not helplife2.net?

My teacher for my Calculus class in high school required that we choose a topic that relates to mathematics and discuss it for a whole class period (near 40 minutes). I chose a physics-related topic... Basically its how to determine the range of a golf ball... And I want to do it reasonably accurate, including air resistance, lift from the magnus effect, and so on, it only needs to be a 2D model, I am thinking. I only just now got to the part in physics discussing forces...we haven't even really gone into how forces affect positioning and velocity and acceleration. I know that there should be a lot of calculus in it. I know how to differentiate, and I am just now learning how to integrate.

So what I am asking for I guess, are some resources for figuring out how to do all of these things, preferably online resources. That go through the math and the theory of it. All help would be greatly appreciated.

'Calculus class'

I lol'd, nuff said.


Anyway, just think about the situation, and use Google.

E=MC2

That's all you need.

 

[Hazar]

you fail in even the simplest things pitz, E = MC^2 + 1/2 MV^2

Well, just remember that any teacher has an equal and opposite teacher.

Thanks Halflife2.net, you never fail at failing. No but really, I figured out just how complicated this really is...and I'm just gonna BS my way through it kinda, I already talked to my teacher and he agrees, so everything is cool.

I recall my physics and/or calculus teacher mentioning that exact problem... and yeah, it's pretty complicated how they design the dents on the ball for aerodynamics and stuff. Good luck with your project.

if your position function is modeled as some x(t) the velocity will be x'(t) and the acceleration will be x''(t)
therefore

m*x''(t) = sigma (forces), a good example of this would be the oscillation function of a spring , it would look something like this :

m*x''(t) = -Kx(t) -Beta x'(t)

so the differential becomes

m*x''(t) + Beta x'(t) + Kx(t) = 0

note: beta is the dampening coefficient which represents a retarding force (similar to air resistance) which is proportional to the velocity (the x'(t) ) of the position function.

The unknown x(t) represents the displacement from equilibrium , the equation above contains a single function and one or more of its derivatives so its called a differential function . i doubt that you're actually going to learn to solve such functions in high school but its definitely something you can talk about.

You've got problems? YOU'VE GOT PROBLEMS? The US economy is spiraling out of control due to the financial market's private sector's bad lending habits, burdened on top by members of OPEC and other foreign nations' hostile aggression toward the US dollar, as well as declining respect among European and Asian markets and you think YOU'VE got problems?
