If a car moving with a speed of 50km per hour can be stopped by brakes after at least 6 m what is the minimum stopping distance of the same car if it is moving at a speed of 100km per hour?
NIRAJMALL
we have v2- v02 = 2 a delta x at the first situation we have v= 0 ( final speed) v0= 50 ( km/ h ) = 13.9 ( m/ s ) ( initial speed ) delta x ( stopping distance ) = 6 m so a ( acceleration ) = - 16.1 ( m / s2) ( minus acceleration because speed is decreasing ) in the next situation by supposing that we have the same negative acceleration we have v=0 v0= 100 ( km / h ) = 27. 8 ( m / s ) a = - 16.1 ( m/s2) so delta x will be = 24.0 m ( stopping distance with 100 km/h speed )

What factors determine the stopping distance?
Speed, reaction time, car's mass, tires, mechanical condition & type of brakes.
What determines the stopping distance?
Stopping distance as in braking distance: Braking distance refers to the distance a vehicle will travel from the point where the brakes are fully applied to when it comes to a complete stop. It is affected by the original speed of the vehicle, the type of brake system in use, the reaction time of the driver/rider and the cefficient of friction between the tires and the road surface.
How does friction affect the motion of a vehicle in the context of tire surface road conditions including skidding braking force braking distance thinking distance and stopping distance?
Tyre surface: If the tyre is new, it will have surface with depressions which will offer more friction compared to old tyre whose surface-depressions are worn out and it is more flat, so it offers less friction. Therefore, new tyre will have less stopping distance, as force of friction is more. Thinking distance is affected neither by friction between tyre and road, nor by friction between brake and tyre. If road has a wet surface, it has less friction so the vehicle will skid farther, and vice versa. The braking force, i.e, friction between tyre and brake is unaffected by road condition or tyre surface. Hence the distance the vehicle travels WHILE retarding due to "braking force", is not same as stopping distance, because even when the wheels are stopped rotating due to braking force, the car will skid a little distance- this total distance is the stopping distance.
What energy changes takes place when a moving car is stopped by brakes?
potential energy
Why are stopping distances for braking cars increased on wet roads?
The water gets into the brakes and when you stop there is less friction.
Do air brakes increase your stopping distance?
In general they SHORTEN your stopping distance as they can apply more force to the breaks.
Why are larger brakes prefered over smaller brakes in vehicles?
Larger brakes = shorter stopping distance.
What does stopping distances mean?
stopping distance is the distance it takes for a vehicle to come to a full stop from the moment you apply the brakes
Can i drive with no rear brakes?
No. Your stopping distance will almost double.
What is the stopping distance of a car over 2200 kilos?
Depends on how hard you press the brakes
Under favorable circumstances including reaction time a motor vehicle with good brakes going 50 miles per hour can be stopped within how many feet?
The typical BREAKING distance from 50mph is 38meters, but the overall stopping distance is 53meters (overall stopping distance is made up of thinking distance, which is 15meters in this case, + breaking distance)
What does your total stopping distance includes?
The total stopping distance includes the perception distance, reaction time and braking distance. The distance that your vehicle is traveling and then pressing on the brake after seeing a hazard, is the total stopping distance.
Do drum brakes work better than disk brakes?
No, they are inferior to disc brakes. Drum brakes were used from the beginning of the auto up until the late 60s. Drum brakes are more prone to overheating than disc brakes. Disc brakes also shed water much better than drum brakes which improves stopping distance in wet conditions. Disc brakes apply pressure more evenly than drum brakes thus improving stopping distance. Disc brakes are superior in every way.
How much is the stopping distance for 70 miles per hour?
It depends on the road conditions, as well the state of your brakes.
Why does myour car shack when you are stopped?
if you car shakes when its fully stopped it may be the harmonic balancer, take it to a garage. is it shakes only when you are braking while stopping than have you brakes checked
Do front or rear brakes have more stopping power?
Front brakes have significantly more stopping power than rear brakes.
What is braking distance composed of?
Braking distance is usually measured by how fast you can stop at 60mph, 60-0, the make of a car is the factor of the stopping distance, each car varies. Your car can have disc brakes or drum brakes or both. Disc brakes are more effective than drum brakes. But braking distance is usually showed by how many feet it takes to stop from 60mph
