How about for Division C?
It can't hurt to know it, but it's not something you should focus on.
You do have a binder, so its okay to put in really obscure things that you think might just come up.
2010: 5th in NYS
2011: 4th in NYS
2012: 3rd in NYS

Yeah, but somtimes it's hard to utilize something that's in the binder if you've never practiced with it before or done a sample problem.

Well, as long as I know the equation it's fairly simple to plug in the numbers. But for conceptual things, that's a different story.

I understand the Doppler Effect qualitatively, but could someone please help me understand how to do quantitative problems with it?

Check out the Wikipedia page: http://en.wikipedia.org/wiki/Doppler_effect
It's got some good formulas and links to other sites that let you simulate it.

So do we use the formula for the Doppler Effect in classical physics:



or must we adjust this because we are working with light, rather than sound?

You only need to use the relativistic doppler equation when one of the objects is moving near the speed of light.

Is it true that this year, they're going to make Div B reflect on 2 mirrors for the Laser Shoot as opposed to 1?

Physics is difficult for 99% of the world's population because they don't understand it. The other 1% know too much.

Not true. You have the OPTION of using up to 5 mirrors, but nothing in the rules 'makes' you use 2.

...That requires more thought than I had previously given it...better get my partner cracking...
