Which of the following factors has direct influence on the stopping distance of the passenger car?
aThe driver's reaction time.
bThe weight of the passengers.
cThe weight of the vehicle.
Why?
Stopping distance includes the distance travelled during the driver's reaction time and the braking distance. A longer reaction time means the car travels further before braking begins. This makes A correct, while the mass of the passengers or vehicle alone does not determine stopping distance.
