The distance needs to be further apart from the car in front

How long does it take to stop a car going 20 mph?
That depends upon the braking ability of the car, the condition of the tyres and road surface. Also the alertness of the driver will have some effect. If you are referring to the emergency stopping distance as suggested by the UK Government in The Highway Code publication (which has not been updated for modern cars) for a dry road and a car with good brakes and tyres, then the stopping distance is 20ft for the thinking distance plus an actual stopping distance of 20ft making a total of 40ft. The table of stopping distances is given by: d = speed + speed2 ÷ 20 where the distance d is in feet and speed is in mph. At 70mph this equates to 315 feet ~= 96m which is almost 100 metres - the distance between marker posts along the side of a motorway!
What would your stopping distance be if you are driving 30 miles per hour?
Most cars can stop from 60 mph in about 100 feet or so. If the relationship is linear then a car should stop from 30 mph in about 50 feet.
How are cars related to math?
Wheels have rpm's (rotation per minute) and you can calculate that by using the circumference formula to find the total length around the wheel. If you have a specific distance you want to cover, divide that distance by the circumference to find the RPM. Or if tires have a maximum capacity it can hold, you'd have to calculate the total weight of the car and compare it to the all four or 6 of the tire's maximum capacity to see if the tires can adequately hold and support the car.
A train with two hundred cars takes miles to stop?
Yes, it can. Train braking systems are not that powerful and a large train can take over a mile to come to a stop.Consider the physics. The kinetic energy of a train is given by: KE = 1/2 m v2The work to stop a train is F d, where F is the stopping force provided by the brakes and d is distance.So F d = 1/2 m v2. This tells you that if you double the speed of the train, you increase the stopping distance by 4 fold! If you double the mass of the train (the number of cars) you double the stopping distance.The web site below gives some figures on train braking distance.http://homepage.ntlworld.com/wilf.james/trains.htm
Why don't the cars follow a straight line down the front straight?
At the beginning of the race the cars are warming the rubber of their tires. Later they are preparing for turns, trying to minimized the angle of turn on the first turn.
What is the stopping distance of a truck vs a car?
As trucks are generally heavier than cars they require a longer distance to stop.
What is the stopping distance at 60 mph?
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.
How many tires are on 26 cars?
If they are normal cars there will be 104 tires
Determine the stopping distance by these factors?
The two major factors are; friction between tires and road; friction between brake pads and rotors. Wind speed plays a small role that is usually much less of an effect than the aforementioned.
How are thinking distance and braking distance linked?
When you will observe the road far ahead of the front end of your car and keep proper distance between other cars, then you will have enough time for thinking and enough space for braking. But when intense situation happens, then the thinking and braking are solidified in one desperate move: to avoid a collision.
Slow down and plan for at least times the normal stopping distance if it begins to rain while you are driving?
Rain The first few drops of rain mean danger. Roads are most slippery just after the rain begins because oil dropped from cars has not been washed away. Slow down and plan for at least two times the normal stopping distance. In a heavy rain, your tires can ride on a thin film of water, like skis. This is called hydroplaning. When your tires are not touching the road, you can easily lose control and skid. Keep your tires on the road by slowing down when it rains, and by having tires with the right air pressure and good tread. Brakes often become wet after driving through deep water or driving in heavy rain. They may pull to one side or the other, or they may not hold at all. If this happens, slow down and gently push on the brake pedal until your brakes are working again.
When did cars start having rubber tires?
Since cars were first made tires were always rubber.
What is the overall stopping distance for a car at 30- 12 6 23 or 41 meters?
depends on how heavy the cars is. depend on the brakes and the tire performance
How does a burn out ruin tires on race cars?
A burn out will ruin tires on race cars by burning up the rubber. The rubber of the tires will get worn from the friction of the pavement causing the tires to tear.
Do any European cars need 14 inch tires?
Many European cars use 14 inch tires.
Why do cars slip on wet road?
the tires are made of rubber. when rubber gets wet, it gets slippery, which means less friction from the tires to the ground, making it easy for the car to keep going instead of stopping. also, a car is very heavy, so momentum definitely kicks in ALOT. think of it this way. car tires that are dry + dry land = alot of friction and quick stopping. but make every thing slippery and the friction goes away.
What do cars travel on?
Tires or the road.
