Homework Statement
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?
Homework Equations
F(centripetal)= (mv^2)/r
F(static) = Mu(normal force)
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 ~_~
