Homework Help: Stupidly tough frictional force problem

  1. Nov 6, 2007 #1
    1. The problem statement, all variables and given/known data

    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.

    2. Relevant equations

    g = 9.8m/s^2.

    3. The attempt at a solution

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