Given information
We are given that:-
The distance the car skids before coming to rest, .
The coefficient of kinetic friction between rubber and the pavement, .
Step-by-step explanation
Step 1.
Assume that kinetic friction is the net force causing the deceleration. See the free body diagram for the car, assuming that the right is the positive direction and the direction of motion of the skidding car.
There is no acceleration in the vertical direction, so
Applying Newton’s second law to the direction gives the following:-
Frictional force:-
Third equation of motion is
