What's confusing me is that both forces are supposed to be pointed downward toward the middle of the hill. So we're treating centripetal force as going back out to the car? I know that intuitively the car will want to (if it's going fast enough) lift off the hill, therefore reducing the weight...
I'm bypassing the normal questions, only because I have already solved the question, but want help figuring out why the answer is what it is (without incorporating numbers into it at all).
The idea is that a car is at the top of a hill going a constant speed. We are to treat the hill as having...
Don't let the problem tell you if there are triangles in there or not. If you can't find any, make some.
Do you know how to solve vector addition problems with components (ie, making some easy right triangles out of vectors)? That's where you'll want to start.
