I understand why when deriving the formulas for cars on banked curves, the net force in the Y direction is zero. However, when I google how to derive them, people say that there is a net force greater than zero in the X direction. This is not what my professor says in his explanations however: he says that the net force in the X direction is also zero, and that this is because there is a centrifugal force equal to mv^2/r pointed to the left that cancels Fnsintheta..
I will attach the following diagram to better explain my question. Note the mv^2/r that is pointing to the left, where typically other diagrams do not include that.
All in all, why is the net force in the X direction for my professors explanation equal to zero, where other explanations say it is not?
