How do you calculate braking and stopping distance?
Stopping distance = thinking distance + braking distance Thinking distance is approximately 1 foot for every mph you travel at, for example, a car travelling at 30mph will travel 30 feet before the brakes are applied.
How do you calculate the braking time?
60 MPH = 88 fps. (fps=1.467 * MPH). If the vehicle deceleration rate is 20 fpsps (rather than the previously calculated 15 fps), then stopping time = 88/20 = 4.4 seconds.
What can affect braking distance?
The braking distance of a vehicle can be affected by:
- poor road and weather conditions, such as wet or icy roads.
- poor vehicle conditions, such as worn brakes or worn tyres.
- a greater speed.
- the car’s mass – more mass means a greater braking distance.
What increases braking distance?
The braking distance of a vehicle can be increased by: poor road and weather conditions, such as gravel, or wet or icy roads – less friction between tyres and the road. more mass in the vehicle (extra passengers for example) – the braking friction has to work for a greater distance to remove the larger kinetic energy.
What do you need to know about braking distance?
The following driving safety tips will help you understand what kind of braking distance you can expect from your vehicle and how speed affects how long it will take you to bring your car to a complete stop. Braking Distance: “Braking distance” is the distance your car travels after the car brakes have been applied.
How is the stopping distance of a car calculated?
Stopping Distance: The term “stopping distance” takes into account the distance you travel before you hit the car brake system (reaction distance) plus the distance you travel while the brakes slow you down (braking distance).
What is the stopping distance at 60 mph?
Virtually all current production vehicles’ published road braking performance tests indicate stopping distances from 60 mph that are typically 120 to 140 feet, slightly less than half of the projected safety distances.
What happens if you take a curve too fast?
If you take a curve too fast, your tires can lose traction with the road. This could cause your vehicle to skid off the road or roll over. Tests show that trucks with a high center of gravity can roll over at the posted speed limit for a curve.
