Knowing that the coefficient of static friction between the tires and the road is 0.80 for the
car as shown in figure 2. At this car, suddenly brakes are applied when it was moving with
a velocity of 360 inches/sec and it skidded to rest in 240 inches. Determine the magnitude of the normal
reaction and of the friction force at each wheel as the car skidded to rest.

Answer:
The coefficient of kinetic friction is the ratio of the kinetic friction force (F) between the surfaces in contact during movement to the normal force Ff/N. ... For a given pair of surfaces, the coefficient of static friction is larger than the kinetic friction. The coefficient of friction depends on the materials used.
