The distance required for a car to come to a complete stop depends on various factors, including the initial speed of the car, the braking capabilities of the car, road conditions, and the driver's reaction time. However, I can provide you with some general estimates for the stopping distances at different speeds based on typical conditions. Please note that these estimates may vary depending on the factors mentioned above.
Here are approximate stopping distances for a typical passenger car on dry pavement:
- At a speed of 32 km/h (20 mph): Approximately 6-9 meters (20-30 feet)
- At a speed of 48 km/h (30 mph): Approximately 12-18 meters (40-60 feet)
- At a speed of 64 km/h (40 mph): Approximately 24-36 meters (80-120 feet)
- At a speed of 80 km/h (50 mph): Approximately 38-54 meters (125-180 feet)
- At a speed of 96 km/h (60 mph): Approximately 55-73 meters (180-240 feet)
- At a speed of 112 km/h (70 mph): Approximately 75-95 meters (245-310 feet)
These estimates assume that the driver applies the brakes promptly and effectively, and the road conditions are dry with good traction. It's important to keep in mind that these distances are rough estimates and can vary depending on the specific circumstances. Additionally, it's crucial to always maintain a safe following distance and be prepared to adjust your stopping distance based on the road conditions and other factors.
