B1: The coefficient of static friction between the road and a car tire is 0.7. The coefficient of kinetic friction is 0.55. The mass of a car is 1500 kg.
a. Calculate the maximum static friction force possible between the car’s tires and the road.
b. Calculate the kinetic friction force between the car’s tires and the road.
When you apply the brakes, the friction between the tires and the road is the net force (ignoring air resistance and other
complicating factors).
c. Calculate the car’s acceleration while braking if it doesn’t skid (i. e. static friction).
d. Calculate the car’s acceleration while braking if it does skid (i. e. kinetic friction).
