Final answer:
To determine the coefficient of friction between the car tires and the road surface, you can use the equation: friction force = coefficient of friction * normal force.
Step-by-step explanation:
To determine the coefficient of friction between the car tires and the road surface, we can use the equation:
friction force = coefficient of friction * normal force
First, we need to find the normal force on the car. The normal force is equal to the weight of the car, which is given by weight = mass * acceleration due to gravity. Once we have the normal force, we can use the given skidding distance and initial speed to calculate the friction force. Finally, we can rearrange the equation to solve for the coefficient of friction: coefficient of friction = friction force / normal force.
