Motion around a banked track

  1. Nov 10, 2009 #1
    1. The problem statement, all variables and given/known data
    An object travels around a circular track with a given radius that is banked/inclined (inward) at a given angle. Find the ideal velocity for the object to travel around the track (so that it does not slide up or down but stays in the middle) with no friction or with a given friction coefficient.


    2. Relevant equations

    I have no idea how to begin to solve this or where to begin.

    3. The attempt at a solution

    Start by drawing a free-body diagram, identifying all forces, and writing Newton's law for both the x and the y directions.

    I have done this, but I want to know how i would take the incline of the track into account. The problem would be simple enough if it was on a flat track.

    You need to account for the incline to draw gravity and the normal force at the correct angle to each other. Just draw the incline, draw the car, and analyze away.
