(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A 600 kg car is going over a curve with radius 120m that is banked at angle of 25 degrees with speed of 30 m/s. The coefficient of static friction between car and road is 0.3. What is the normal force?

2. Relevant equations

F(centripetal)= (mv^2)/r

F(static) = Mu(normal force)

3. The attempt at a solution

I think that the centripetal force is equal to the friction force. So I can just substitute centripetal force for friction. But my teacher also said that is a parallel force but I'm not sure it is. From the free-body diagram, I will get..

F(c)= (Friction + Parallel force) Cos(angle)

I'm actually quite confused ~_~
