A bus which speed is 20 ms starts braking at a ratio of 3ms each second. Find the distance is travels before stopping.?
To find the distance the bus travels before stopping, we need to calculate the total time it takes to stop. The bus decelerates at 3 m/s^2, so it will take about 6.67 seconds to come to a complete stop (20 m/s divided by 3 m/s^2). Using the formula for distance traveled while decelerating (d = v_i * t - 0.5 * a * t^2), the bus will travel approximately 66.67 meters before stopping.

Is reaction time or braking distance most critical factor in avoiding a collision?
Braking distance is usually the critical factor in avoiding a collision, as it determines the distance a vehicle travels before coming to a complete stop after the brakes are applied. Reaction time is important too, as it influences how quickly a driver can respond to a situation and apply the brakes, but braking distance ultimately determines if a collision can be avoided.
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 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 road surface has longest braking distance?
A road surface with loose gravel or sand tends to have the longest braking distance due to the reduced tire traction. When braking on loose surfaces, vehicles are more likely to skid before coming to a complete stop, increasing the distance required to brake.
As a vehicle and speed increases the stopping distance .?
As a vehicle's speed increases, the stopping distance also increases. This is because the vehicle will continue to travel a greater distance before coming to a complete stop once the brakes are applied. It is important to consider this increase in stopping distance when driving at higher speeds to ensure safety on the road.
What thee things add up to stopping distance?
Stopping distance is comprised of three main components: perception distance, reaction distance, and braking distance. Perception distance is the distance a vehicle travels while the driver recognizes a need to stop. Reaction distance is the distance covered during the driver's reaction time before applying the brakes. Finally, braking distance is the distance the vehicle travels from the moment the brakes are applied until it comes to a complete stop.
What are three factors of total stopping distance with hydraulic brakes?
The three factors of total stopping distance with hydraulic brakes are perception time, reaction time, and braking distance. Perception time is the duration it takes for a driver to recognize a need to stop, while reaction time is the time taken to physically respond by applying the brakes. Braking distance is the distance a vehicle travels from the point the brakes are applied until it comes to a complete stop, influenced by factors like vehicle speed, road conditions, and brake effectiveness. Together, these elements determine how far a vehicle will travel before stopping.

What does stopping distance mean for road safety?
The stopping distance is the distance between the driver and the traffic lights which is required to come to a complete stop. There are many factors which are involved in the stopping distance of the car, such as: Weather, Braking systems and Tyre Threading. There are many more, but these are the main ones. If a driver wants to come to a complete stop before driving over the traffic line or causing an accident he/she needs to be on high alert and apply the brakes at a good distance at the right time.

When you drive 3 times faster the distance traveled before you can bring your vehicle to a full stop while applying the brakes will be?
When you drive three times faster, the distance required to come to a full stop increases by a factor of nine, due to the physics of braking. This is because stopping distance is proportional to the square of the speed. Therefore, if you triple your speed, the stopping distance becomes three squared, which is nine times the original distance.
What road surface has longest braking distance?
A road surface with loose gravel or sand tends to have the longest braking distance due to the reduced tire traction. When braking on loose surfaces, vehicles are more likely to skid before coming to a complete stop, increasing the distance required to brake.
At 80 kmp What is the shortest total distance a car travels before stopping on dry road?
Approximately 50 metres. There are other variable to take into account. For instance; The type of surface The tyres The brakes The weight of the car and contents. All these will alter the distance significantly.
As a vehicle and speed increases the stopping distance .?
As a vehicle's speed increases, the stopping distance also increases. This is because the vehicle will continue to travel a greater distance before coming to a complete stop once the brakes are applied. It is important to consider this increase in stopping distance when driving at higher speeds to ensure safety on the road.
