Hi everyone. :) My first post here! Anyway, I have a Physics12AP question that I would like some help with. I've been thinking about it for a long time but I have not been able to solve it.(adsbygoogle = window.adsbygoogle || []).push({});

Here's the problem:

A car on a horizontal road makes an emergency stop such that all four wheels lock and skid. The coefficient of friction is m=0.40. The wheels are 4.2 m apart. The centre of mass is 1.8 m behind the 0.75 m above the front axle (we are looking at two wheels at the side of a car). The car weighs 11,000 N. Calculate acceleration of the car, and normal force and friction force of each wheel.

Hint: The 11,000 N of weight is NOT evenly distributed.

There's the question, any help would be much appreciated! :) Thanks in advance guys.

EDIT: The work I have done so far is not helping at all, I've tried using pythagorus, FN=ma, FF=MFN. I don't really know how to get started with it...
