How many seconds will it take for a car to stop if it is traveling at a speed of 40 miles per hour?
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.
You are driving at a speed of 20 meters per second and decelerate at a constant rate stopping in 4 seconds How far do you ravel while stopping?
Initial speed = 20 m/sFinal speed = 0Average speed = 10 m/sDistance = (average speed) x (time) = 10 x 4 = 40 meters .
A car slows down uniformly from 30.0 meter per seconds to rest in 7.20 seconds how far did it travel while decelerating?
Its average speed was 1/2 of (30 + 0) = 15 meters per second.Distance = (average speed) x (time) = 15 x 7.2 = 108 meters .

30 km/h
What does dwt mean?
DWT means driving while texting.
Always keep your eyes moving while driving by checking your mirrors every how many seconds?
2-5 seconds
How quickly does a person perceive and then react to a driving hazard?
It all depends on the persons reaction time. Some people can react in under a second while others take up to 3 seconds to realize what has happened.
How many minutes in a mile while driving 76 mph?
51.429 seconds (rounded)
How are your lives affected by driving while texting?
Driving while texting greatly reduces the driver's reaction time and will therefore put more lives at risk.

How often should you check your mirrors while driving?
i heard it was every 3-4 seconds :) which is heaps
If it's raining and you are tired while driving how many seconds of following distance should you use?
Usually in good conditions you want to have 2-3 seconds of distance between you and the car in front of you, for every hindrance (ie. rain) you add one second of distance. So in your case being both tired and having to deal with rain, i would say have at least 5+ seconds distance. I wouldn't recommend driving while sleepy as your reaction time and judgment decreases while tired, if you think you are getting too tired please pull over and take a quick nap.

The driving force of a reaction is the change in?
The driving force of a reaction is the change in free energy. This change determines whether a reaction will proceed spontaneously or require external energy input. A negative change in free energy indicates a spontaneous reaction, while a positive change requires energy input.
What is reaction time when driving?
The definition of reaction time, in terms of driving, is how long it takes you to react to an emergency: by hitting the brakes, turning the wheel, etc.For most people, this time is approximately 1 second, which at a speed of 60 mph is about 90 feet. So if the emergency occurs within that distance, you probably won't have had time to avoid the accident.Many insurance companies, however, use a much stricter standard of 1.5 seconds (135 feet), this being (on average) the amount of time it takes to recognize an emergency, decide upon an action, and then execute it.This is one reason why you're supposed to keep a minimum of four car lengths (2 seconds) between you and the car you're following while at freeway speeds.
