For a car with good brakes and a length of 4m, a dry road with a driver with average reaction time it will take approximately 36m/118 feet/nine car lengths for it to stop. This can be divided up into two sections the thinking distance/reaction distance of 12m and a braking distance of 24m. Like the previous answer stated the braking distance can be changed depending on the road surface type and weather conditions or if the car is fitted with an Anti-lock Braking System Thinking distance can be increased by drinking alcohol or taking some types of drugs.
If a car is traveling at a speed of 30 mph, it would take approximately 44 feet to come to a complete stop. This is calculated based on the average reaction time of 1.5 seconds and an average braking distance of around 110 feet at this speed.
Stopping distances are measured in feet not in seconds. At 40 mph you're traveling 58.7 feet per second. The average driver reaction time is about 3/4 second which equates to 44 feet. After applying the brakes it will take approximately 82 feet to stop the vehicle. The total stopping distance for a car traveling 40 mph will be 126 feet when you include reaction time and actual stopping distance of the vehicle. If you divide 126' x 58.7' which is the distance traveled per second you get 2.14 seconds. This is assuming you're paying attention and have average reaction time while driving.
Can't answer without the distance to target.
Feet refers to a distance while seconds is time, so you can't say that there are a certain number of feet in one second. You can however say that you travel a certain number of feet in one second, but that number depends on the velocity that you are traveling at.
When traveling 30-mph, the braking distance is 45-feet, and the total stopping distance is 75-feet. This is the length of a semi-truck and trailer.
On dry pavement in the average car it will take 60 ft of thinking about it, & 180 ft of braking for a total of 240 ft. Double the braking distance on wet pavement for a total of 420 ft. On snow it is anyone's guess.
About 275 feet
The total stopping distance includes the perception distance, reaction time and braking distance. The distance that your vehicle is traveling and then pressing on the brake after seeing a hazard, is the total stopping distance.
On dry, level pavement, with decent tires? About 120 feet. Many things affect this calculation. With worn tires the distance can increase to 210 feet. Dirt roads require longer braking distances than pavement. Ice can increase the braking distance by hundreds of feet. Braking down a hill, depending upon the slope, can double the braking distance, whereas braking up hill can halve that distance. If you lock the tires, you typically increase the braking distance. You can reduce the distance by pumping the brakes. Anti-lock brakes allow the tires to slip, which decreases the braking distance. Extra weight in the vehicle increases the braking distance. Refer to the link below for calculating the braking distance at different speeds with different tire wear on dry, level pavement.
The approximate distance from California to Maine is 17,645,918.4 feet or 3,342 miles.
Depends entirely on the size of the vehicle. The average stopping distance for a vehicle is around 160 feet. That includes 51 feet you will travel during your reaction time. And 109 feet braking distance.
Braking distance is usually measured by how fast you can stop at 60mph, 60-0, the make of a car is the factor of the stopping distance, each car varies. Your car can have disc brakes or drum brakes or both. Disc brakes are more effective than drum brakes. But braking distance is usually showed by how many feet it takes to stop from 60mph
