Final answer:
All factors such as vehicle speed, tire-road friction, driver condition, vehicle weight, and brake condition influence the total stopping distance. The stopping distance is affected by the distance covered during the driver's reaction time and braking distance once the brakes are applied.
Step-by-step explanation:
The factors that have an influence on the total stopping distance of a vehicle include the speed at which the vehicle is moving, the friction between the tires and the road surface, the condition of the driver, the weight of the vehicle, and the condition of the brake system. In essence, all of these factors (d. All of the above) play a role in determining the stopping distance.
When calculating the stopping distance, we need to account for both the distance the vehicle travels during the driver's reaction time and the distance it travels while the brakes are being applied. For instance, if we have a car initially traveling at 30.0 m/s with a driver reaction time of 0.500 s, it is reasonable to assume the velocity remains constant during the driver's reaction time, and this affects the total stopping distance.
