The front brake pads on your car wear out faster than the rearbrakepads; in fact, some cars are specifically designed with largefrontbrake pads because of this. This results from the fact thatwhen acar is braking the magnitude of the friction force acting onthefront wheels of the car is larger than the magnitude of thefrictionforce acting on the rear wheels of the car. Consider a carthat hasa mass of 1500 kg that is decelerating (by using thebrakes) at arate of 0.25 g. The distance between the front andrear axles is 2.8m and the center of mass of the car is directlyin-between the twoaxles at a height of 0.6 m above the ground.What is the ratio ofthe force of friction acting on the fronttires to the force offriction acting on the rear tires? Assumethat the coefficients offriction between the tires and the roadare the same for all tiresand, for simplicity, assume that the caris skidding as itdecelerates.
