Drivers must pament interest to their environment. This includes calculating the braking distance from the cars and objects encompassing a Chauffeur. Astute your van's the braking distance to avoid accidents can save lives and cash.
Instructions
1. Complete the hurry the motorcar is traveling--the higher the quickness, the more advantageous the braking distance. For this case history, a quickness of 70 miles per date Testament be used.
2. Fix the stopping distance. This is the distance from your vehivle to the entity in front of it. To estimate stopping distance when driving, enshrine that the customary machine length is 15 feet. So four machine lengths is roughly Identical to 60 feet. When driving 70 mph, the stopping distance is 102.7 feet per moment (fps = 1.467 x mph).
3. Academy a deceleration rate. This is the rate that applying the brakes slows the vehicle. This rate is typically 20 feet per second.
4. Establish the stopping time. Calculate the total braking distance. This formula is 1/2 the initial velocity in feet per second multiplied by the time required to stop, which is 0.5 x 102.7 x 5.135 = 263.68. The calculated thinking distance is 2 x 102.7 = 205.4. Add the two numbers together. 469.08 feet is the total braking distance.
Reaction time can take an average of 2 seconds to set in and realize that there is a problem. The reaction time can vary given the age of the driver, condition of the car, distraction in the vehicle and condition of the road. The formula to make a precise calculation 102.7 fps x 2 (reaction time in seconds) = 205.4.
6. When traveling at 70 mph, which equals 102.7 feet per second if the deceleration rate is 20 fps, the stopping time equals 102.7/20 = 5.135 seconds.5. Ascertain the thinking distance, which is reaction time as it relates to distance.
