The minimum braking distance for a car is tested on a dry road. The test is then repeated on a wet road. What happens to the braking distance and to the frictional force between the tyres and the road?
Abraking distance: decreases, frictional force: decreases
Bbraking distance: decreases, frictional force: increases
Cbraking distance: increases, frictional force: decreases
Dbraking distance: increases, frictional force: increases
✓ Correct answer
C: braking distance: increases, frictional force: decreases
