How would I solve a problem like this.

    I was just wondering how you would solve how far a car would travel on a street with an initial velocity with a a high coefficient of friction. Its not homework or anything. How would you solve a problem like this?

    [tex]F=\mu N[/tex]

    [tex]v^{2}_{f}=v^{2}_{i} + 2 a d[/tex]

    Then do algebra.

    Be carefull, if the coefficient of friction is too high the car will not move, lol.

    But its simple:x = vt + 1/2at^2
    To find a in the above equation= Force of friction = umg, To make it simple, assume constant motion in a straight line. therefore, foward force = force of friction
    umg= ma, m cancels therfore, a=ug, you know u and solve for a! Insert into above equation.
