If a child ran into the road 65 to 70 feet ahead of your vehicle what is the highest speed from which you could stop with good brakes before hitting him?
You could stop at 20 miles per hour without hitting him.
---------------------
Assuming The Highway Code formula for stopping distances:
stopping_distance = thinking distance + stopping time
= speed + speed²/20 ft (where speed is in mph)
→ 65 = speed + speed²/20
→ speed² + 20speed + 1300 = 0
→ speed = -10 + 10√14 mph ≈ 27.4 mph
(The negative square root can be ignored as it gives a negative speed which is nonsense for this problem.)
However, this assumes that you observe, think and can start braking within 15/22 (≈ 0.68) seconds of the child running into the road (1ft for every 1 mph of speed), and your braking matches the Highway Code assumptions for good tyres, brakes and dry road conditions.
What else can I help you with?
What are the different types of brakes?
The main types of brakes are disc brakes, drum brakes, and regenerative brakes. Disc brakes use calipers to squeeze pads against a rotor to create friction and slow down the vehicle. Drum brakes use shoes to press against the inside of a drum to generate friction. Regenerative brakes convert kinetic energy into electrical energy to slow down the vehicle.
Do car brakes reduce friction?
No, car brakes actually increase friction in order to slow down or stop the vehicle. When the brakes are applied, they create friction between the brake pads and the brake rotors, converting the kinetic energy of the moving vehicle into heat energy that dissipates, causing the vehicle to slow down.
What mechanical motion principle do the brakes in a car or on a bicycle use?
The brakes in a car or bicycle use the mechanical motion principle of friction to slow down or stop the vehicle. When the brake is applied, friction is generated between the brake pads and the rotor (for disc brakes) or the wheel rim (for rim brakes), converting kinetic energy into heat and bringing the vehicle to a stop.
How do anti-lock brakes enable a vehicle to stop more quickly compared to conventional brakes?
Anti-lock brakes enable a vehicle to stop more quickly compared to conventional brakes by preventing the wheels from locking up during hard braking. This allows the driver to maintain steering control and avoid skidding, resulting in a shorter stopping distance.
When you apply the brakes what kind of friction is that?
When you apply the brakes, you are experiencing kinetic friction between the brake pads and the brake rotors. This friction converts the kinetic energy of the moving vehicle into thermal energy, which helps slow down the vehicle.
What should you AVOID doing if your vehicle begins to hydroplane?
Avoid hitting the brakes.
If a child runs into the road 45 to 50 feet ahead of your car what is the highest speed from which you can stop with good brakes without hitting him?
15 mph
Why use air brake in heavy equipment?
Air brakes allow you to use less force when hitting the brakes. Heavy equipment takes a lot of force to make them stop and without the air brakes we would have to use a lot of strength in order to stop the vehicle.
Adjusting abs brakes 98 s-10?
You would adjust the brakes on a vehicle with abs brakes the same way you would adjust the brakes on a vehicle without abs brakes.
When parking headed downhill it is best toIf a child ran into the road 65 to 70 feet ahead of your vehicle what is the highest speed from which you could stop with good brakes before hitting him?
When parking headed downhill, it is best to turn your front wheels toward the curb and set the parking brake to prevent the vehicle from rolling into the street. To determine the highest speed at which you could stop before hitting a child 65 to 70 feet ahead, you should consider your vehicle's stopping distance. At a speed of approximately 20 mph, the total stopping distance (including perception and reaction time) is about 60 feet, which suggests you could stop safely within that distance. However, at higher speeds, the stopping distance increases significantly, making it unsafe to drive faster than 20 mph in this scenario.
Does the 2003 Camry have disc brakes on the rear of the vehicle?
No, the 2003 Camry does not have disc brakes on the rear of the vehicle.
Who is at fault in a rear-ending accident if the person in front slammed on their brakes?
The person who was following too closely to stop before hitting the car ahead.
What is gross trailer weight braked?
This is the maximum amount of weight a vehicle can tow, if what being towed has brakes. A towed vehicle with brakes (electronic brakes) responds to the same braking that the vehicle doing the towing has. If the vehicle being towed does not have brakes, the maximum towing capacity is much less.
Why do you need front brakes?
The front brakes on any vehicle do most of the stopping. When you apply the brakes the weight shifts to the front of the vehicle. For this reason the front brakes are needed more than the rear. Try stopping a vehicle with just the hand brake which applies only the rear brakes.
After you start your vehicle and as you begin to drive always check your?
brakes.
Should tires or brakes stop a vehicle?
Yes, that is the purpose of brakes.
Are brakes and rotors the same component in a vehicle?
No, brakes and rotors are not the same component in a vehicle. Brakes refer to the system that slows down or stops the vehicle, while rotors are the discs that the brake pads press against to create friction and stop the vehicle.
