What is the Normal Force on Tires in a Banked Curve with Friction?

[nns91]

Homework Statement

Radius 150m, angle is 10 degree, mass of the car 800kg, speed 85 km/h.

Find the normal force on the tires exerted by the pavement. ( There is friction)

Homework Equations

$$\Sigma$$ F= m* v^2/r

The Attempt at a Solution

The friction makes it's so complicated. I know that Fn= mg/cos10 will not work.

Can anyone help me ?

It's not that m*g*Cosθ doesn't work, it's just that there is a horizontal force from the angular motion that is acting as well.

If there is a horizontal force, what is its component that is also normal to the incline?

Thanks. I got it.
