Homework Help: Max Acceleration of a Car

  1. Jul 1, 2009 #1
    1. The problem statement, all variables and given/known data

    What is the maximum acceleration a car can undergo if the coefficient of static friction between the tires and the ground is 0.30?

    2. Relevant equations
    sigmaFy = Fn-mg = may = 0
    sigmaFx = Fp - Ffr = max = 0
    Ffr = (mew)s * Fn
    Fp = Ffr = (mew)*Fn
    Fp = (mew)s(mg)

    mg is mass times gravity
    * are multiplication
    (mew)s = static friction
    Fn = normal force

    3. The attempt at a solution

    Um...I have no clue how to solve it, any direction to point me in would be helpful. I can't see how to solve it without the mass of the car, or the initial velocity.

    Nevermind, it was as simple as multiplying the coefficient by gravity, sorry for the space waster.
