Final answer:
The coefficient of static friction is used for antilock brakes to prevent skidding.
Step-by-step explanation:
The coefficient of static friction is used for antilock brakes to prevent skidding. When brakes are applied, the friction between the brakes and the wheels helps to slow down the vehicle. However, if the wheels lock up and start skidding, the vehicle can lose control. By using the coefficient of static friction, antilock brakes can modulate the braking force to maintain traction and prevent skidding.
