Final answer:
The average stopping distance at 35 mph on dry pavement is determined by the sum of the reaction distance, assuming a 0.500-second reaction time, and the braking distance, which depends on multiple factors. The total stopping distance often cited in safety manuals is approximately 106 feet (32.3 meters), but actual conditions may vary.
Step-by-step explanation:
The average stopping distance for a car driving at 35 mph on dry, level pavement is calculated by adding the distance covered during the driver's reaction time to the braking distance. To calculate the reaction distance, we assume the car travels at a constant velocity of 35 mph (which is approximately 15.6 m/s) during the driver's reaction time of 0.500 seconds. This reaction distance is distance = velocity × time = 15.6 m/s × 0.500 s = 7.8 m. The braking distance needs to be calculated separately based on other factors such as the condition of the brakes, tires, and road surface, as well as the car's mass and the coefficient of friction between the tires and the road.
Assuming an exact calculation was provided in the materials (like the one based on a car traveling at 30.0 m/s), we would use a similar approach for the vehicle traveling at 35 mph, adjusting the figures accordingly. Without a specific formula or detailed information such as the coefficient of friction and the condition of the vehicle, it's challenging to provide an exact number for the stopping distance. In many driving safety resources, the overall stopping distance for a car traveling at 35 mph would depend on ideal conditions and be estimated at around 106 feet (32.3 meters), including both reaction and braking distances.
