ANSWER:
Step 1 of 2
Here we need to explain how the measurement of skidding mark length of the car will be useful in estimating the initial speed of the vehicle during the investigation of traffic accident.
The stopping distance of the car which is equal to the skidding mark length depends on the coefficient of kinetic friction between the tires and the road, and the initial speed of the car.
