    I need help deriving a formula to describe the effect to toe in on speed

    At first I thought it might just be a simple equation using cos{\theta} where {\theta} is the degrees of toe in.



    But thats not it. I need to take into account rolling friction.
    The equation for rolling resistance is

    F=cN

    F is the force of rolling friction
    c is the rolling resistance coefficient
    N is the normal force.

    I think it might be along the lines of

    F(final) = Fcos{\theta} - cN

    Here is a pic of what I'm talking about:


    Then I need to relate Force to Velocity.
    Any ideas?
