    Solution
    Here’s how to approach this question

    To create the free body diagram, draw the forces acting on the race car: gravitational force (mg) vertically downward, normal force (N) perpendicular to the banking surface, and the frictional force (fr) parallel to the banking surface.

    Step 1

    Given data,


    speed at turns, v=90 ms

    radius of speedway turn, r=325 m
