What is the link between the braking distance and the thinking distance of stopping a car?
A distracted driver will have a greater reaction time than a non-distracted driver. A distraction to a driver will increase the drivers' reaction time and reduces the ability to respond to an emergency situation. The driver takes longer to react and more time passes between seeing the hazard and starting braking, so the car travels a greater distance before it comes to a stop.
Two important factors to take into account for calculating stopping distances are reaction time and breaking distance.
Reaction time
For average drivers it takes 1.5 seconds to react to an emergency situation. For a distracted driver it may take as long as 3 seconds. A focused driver driving at 60km/hr will travel approximately 25m before they react, and a distracted driver driving at 60km/hr will travel approximately 33m before they react.
Braking distance
The breaking distance of a car depends on a number of variables. The slope of the roadway; a car will stop more quickly if it is traveling uphill because gravity will help slow the vehicle. The frictional resistance between the road and the tyres of the car is also important. A car with new tyres on a dry road will be less likely to skid and will stop more quickly than one with worn tyres on a wet road. If the slope and frictional resistance are equal, the factor that has most influence on braking distance is the initial speed.
Formula used for calculating braking distance:
d = V /(2g(f + G))
Where:
d is the Braking Distance (m)
g is the Acceleration due to gravity (9.8m/s^2)
G is the Roadway grade
V is the Initial vehicle speed (m/s)
f is the Coefficient of friction between the tires and the roadway (u)
A more simple formula used to calculate braking distance can be derived from a general equation of physics. Ignoring friction, and the roadway grade
v = u - 2ad
where:
v is the final velocity (m/s)
u is the initial velocity (m/s)
a is the acceleration (m/s^2)
d is the distance traveled during deceleration(m)
Since we know that v will be zero when the car has stopped, the equation can be re-written as
d = u/2a
The total distance it takes for the car to come to a stop can be found by adding the reaction distance to the braking distance.

What is the thinking distance the braking distance and the overall stopping distance for a veichle travelling at 20mph?
At 20 mph, the average thinking distance is around 20 feet, while the braking distance is approximately 20 feet as well. Therefore, the overall stopping distance for a vehicle traveling at 20 mph would be around 40 feet.
How can one determine the stopping distance of a car?
The stopping distance of a car can be determined by considering the car's speed, reaction time of the driver, and the braking distance required to come to a complete stop. The stopping distance is the sum of the reaction distance (distance traveled during the driver's reaction time) and the braking distance (distance traveled while the brakes are applied). It can be calculated using the formula: Stopping distance Reaction distance Braking distance.
What is meant by the term thinking distance?
Thinking distance refers to the distance a vehicle travels from the moment a driver perceives a hazard until they physically react, such as by braking. It is influenced by factors like reaction time and speed. A longer thinking distance can increase the overall stopping distance of a vehicle.
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.
Does friction affect stopping distance?
Yes, friction plays a significant role in determining stopping distance. The friction between the tires and the road surface creates the braking force needed to slow down or stop a vehicle. The higher the friction, the shorter the stopping distance, and vice versa.
What is the equation that links stopping distance and thinking distance and braking distance?
The equation that links stopping distance, thinking distance, and braking distance is given by: Stopping Distance = Thinking Distance + Braking Distance. Thinking distance is the distance a vehicle travels while the driver reacts to a hazard, while braking distance is the distance traveled while the vehicle comes to a complete stop after the brakes are applied. Together, they represent the total distance required to stop a vehicle safely.
What is the thinking distance the braking distance and the overall stopping distance for a veichle travelling at 20mph?
At 20 mph, the average thinking distance is around 20 feet, while the braking distance is approximately 20 feet as well. Therefore, the overall stopping distance for a vehicle traveling at 20 mph would be around 40 feet.
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.
What is the relationship between a car's mass and its 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

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.
What three things add up total stopping distance?
Perception Distance + Reaction Distance+ Braking Distance.
What tree things add up to total stopping distance?
Perception Distance, Reaction Distance and Braking Distance
Does friction affect stopping distance?
Yes, friction plays a significant role in determining stopping distance. The friction between the tires and the road surface creates the braking force needed to slow down or stop a vehicle. The higher the friction, the shorter the stopping distance, and vice versa.
