Question: It is possible to calculate the coefficient of friction between a vehicles tires and the road by measuring the vehicles stopping distance. A driver moving with speed 70 mph on a level highway slams on her anti-lock brakes. The pavement is wet, and the car covers 83 m (four-fifths of a football field!) before reaching a stop.
Part A: What is the cars acceleration while braking?
Part B: What is the type of friction arising between the tires and the road?
Part C: What is the coefficient of friction between the wet road and the tires?
I need help to find the coefficient of friction between the wet road and the tires.
