Trains require a long stopping distance.
The greater the mass of the car and its occupants the longer the stopping distance that is required for the vehicle. Stopping distance is calculated by taking into account car mass and reaction time in braking
That depends on what vehicle you are stopping from 55 mph. the laws of physics come into play. The heavier the vehicle the longer the stopping distance. So I cannot give an accurate answer except to say that from 60 mph the average for a mid-sized car is around 135 feet.
The steeper the slope, the longer the stopping distance is.
Because the increased weight increases the stopping distance of the vehicle.
longer
Need longer stopping distance.
As trucks are generally heavier than cars they require a longer distance to stop.
The faster you are going the longer the stopping distance is. The slower you are going the shorter the stopping distance is. E.G. Speed of a car Thinking distace Breaking distance Total stopping distance mph meters meters meters 30 9 14 23 40 12 24 36 50 15 38 53 70 21 75 96
Stopping distance is always relative to driving speed. The faster you go, the longer it takes you to stop. And if the road surface is wet or icy it will take even longer to stop. That means you also have to give yourself more space behind other vehicles.
Need longer stopping distance.
It depends on the vehicle, tires, weather and road surface, (Gravel, black top, concrete). Vehicle braking distance by type of car varies greatly: Pickup trucks/ SUVs- range from 145-175ft depending on weight/options, for example- 4x4 1ton being heavier take longer to stop. most cars- 115-135ft. high performance cars- 105-115ft. supercars- 92-105ft, large multi piston caliber, carbon ceramic brakes are almost mandatory for sub 100ft stopping distance.
Longer stopping distances. A passenger car may weigh 3,000 pounds. A large truck may weigh 90,000 pounds. It is much harder to stop.
