So what all can you figure out about this problem? Just sort of throw everything out there that you think might be possibly useful. That way we have somewhere to start from in figuring this out. Can you draw a picture? Can you write down any equations or at least name some possibly useful equations you might have heard about? Anything you know, I'll help you figure it out and understand so it's simple and makes sense. =)
