That all depends upon the deceleration the car experiences.

The more braking there is, the greater the deceleration and the shorter the stopping time.

In the UK Highway Code, travelling at 15 mph under emergency braking it would take 15/22 ≈ 0.68 seconds for the thinking plus 15×3/44 = 1 1/44 ≈ 1.02 seconds for the actual stopping, a total of 1 31/44 ≈ 1.70 seconds (covering 15 + 11¼ = 26¼ ft).

Note that these figures have not been updated in years, but the braking of cars has improved, so you should be able to stop in less time.

If there is constant acceleration and deceleration then it would be 33.3 ft to stop

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.

That depends on how fast the truck is traveling.

The hardest to stop in this case is the vehicle with the largest mass - for example, a big truck.

(change in velocity)/(change in time)=avg. acceleration (-30 m/s)/(15s)= -2 m/s2

Well really it depends on how large the the car is. but at an average it would take about 4 seconds

2 seconds to 5 seconds , long enough to check that all directions are safe.

when traveling at 55mph, how many feet do you need to stop

Well if it accelerates, it speeds up so it won't stop. If you mean decelarate, it decreases 10 ft/s every second, so 50/10 is 5 seconds

When traveling at 35 mph it will take you 210 feet to come to a complete stop

14590 seconds.

That would depend on where you are traveling from.

When traveling at 35 mph it will take you 210 feet to come to a complete stop.

Not many if you are traveling from Blythe, Caliifornia.

Speed= Distance / time => Distance = Speed x Time =16x8 = 128m

If we assume the time it takes for the ball to stop is directly proportional to the height it is dropped from, we can set up a proportion based on the given information. From the given data, we have the ratio of time to height as 11/1 = 25/2. Therefore, if we continue this ratio, the time it would take to stop if dropped from 3 feet would be 55 seconds.

The car at fault would be the one leaving the stop sign because it's failing to yield to the car traveling straight (that is, if the vehicle going straight has no stop sign).
