How Is Maximum Car Acceleration Calculated with a Friction Coefficient of 0.30?

[tbaskerv]

Homework Statement

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

Homework 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

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.
