On a level road the stopping distance for a certain car traveling at 80 km/hr is 32 m. what would be the stopping distance for a car when going down a hill on a 1 : 10 grade? (A grade of 1 : 10 means the elevation drops 1 m for a forward travel of 10 m along the roadway.)

As a car drives with its tires rolling freely without any slippage, the type of friction acting between the tires and the road is 100) a) static friction. b) kinetic friction. c) a combination of static and kinetic friction. d) neither static nor kinetic friction, but some other type of friction. e) it is impossible to tell what type of friction acts in this situation.
