Application of Newton's Law

  1. Oct 15, 2007 #1
    A race car travels 44m/s around a banked (45degree with the horizontal) circular (radius = 200m) track. What is the magnitude of the resultant force in N on the 80 kg driver of this car.

    I've having a hard time setting up the free body diagram.

    First I broke into Fx and Fy

    Fx:

    F - mg*sin(tetha) = 0

    Fy:


    I know i'm going to have to use the Fc = MAc ; Ac=V^2/R
    Fn - mg*cos(tetha) - 0

    I seriously dont know where i'm going with these equations...
