Homework Help: Physics

Posted by zack on Monday, January 14, 2013 at 9:52pm.

The driver of a car on a horizontal road makes an emergency stop by applying the brakes so that all four wheels lock and skid along the road. The coefficient of kinetic friction between tires and road is 0.39. The separation between the front and rear axles is L = 4.1 m, and the center of mass of the car is located at distance d = 1.8 m behind the front axle and distance h = 0.75 m above the road. The car weighs 11 kN. Find the magnitude of the following

I have figured out:
The braking acceleration of the car: 3.822

and looking for:

The normal force on each rear wheel.
N

(c) the normal force on each front wheel.
N

(d) the braking force on each rear wheel.
N

(e) the braking force on each front wheel.
N

I cant quite figure THIS out i know i have to solve through simultaneous equations for F front but i have some mathematical problem ...

Please help !
