Maximize Car Speed on Banked Track: Frictional Force Problem Solution

[magicuniverse]

Homework Statement

A car is driven around a track of radius R=100m which is banked at 30degrees to the horizontal. If the coefficients of static friction between the wheels and the road is Us=0.8, find the maximum speed for the car to stay on the road without skidding sideways.

Homework Equations

g = 9.8m/s^2.

The Attempt at a Solution

Not a clue. Please don't just say split it into comppnets etc... I really don't now how to do this so will need it really explaining to me. Thanks
