When brakes are applied the speed of a train decreases from 96kmh to 48kmh in 800m how muck further will the train move before coming to rest?
The train decelerates at 2 m/s^2 (using the givens). To calculate the distance needed to come to rest, we can use the equation v^2 = u^2 + 2as, where v is final velocity, u is initial velocity, a is acceleration, and s is distance. Rearranging the equation to solve for s, the train will need to travel an additional 800m to come to a complete stop.

Why does a car slide when braking?
A car slides when braking because the friction between the tires and the road decreases, causing the tires to lose grip and skid. This can happen if the brakes are applied too forcefully or if the road surface is slippery.
How does braking affect acceleration in a moving vehicle?
Braking in a moving vehicle decreases acceleration by reducing the speed of the vehicle. When the brakes are applied, friction between the brake pads and the wheels slows down the vehicle, causing a decrease in acceleration.
When does a train's brakes start exerting force on the train's wheels?
A train's brakes start exerting force on the wheels when the brake system is activated by the engineer using either compressed air (pneumatic brakes) or electricity (electric brakes). The force applied by the brakes creates friction between the brake pads and the wheels, which slows down the train.
Which force stops a train when the brakes are applied?
Friction between the brake pads and the train wheels is the force that ultimately stops the train when the brakes are applied. The brake pads create friction by pressing against the rotating wheels, converting the kinetic energy of the train into heat energy as they slow down the train.
What happens to the temperature of a cars brakes when they are applied?
When brakes are applied on a car, the friction between the brake pads and the rotors generates heat. This heat causes the temperature of the brakes to increase significantly, often reaching several hundred degrees Fahrenheit. It is essential to manage this heat buildup to prevent brake fade and maintain braking performance.
How do you use the word brakes in a sentence?
The driver suddenly applied the brakes.
What is an example of a force that decreases motion?
the brakes in your car
Why does a car shimmer when brakes are applied?
no
What relationship could be represented by a graph with a negative slope?
something which decreases over time e.g. speed of a car when the brakes are applied. Time on the x-axis and speed on the y-axis of the graph
Once the brakes have been applied about how many feet does a car which was going 50 mph travel before it comes to a stop?
229 feet
Why do you think a car stops when the brakes are applied?
Friction
What does it mean when the ABS light on a 1994 Ford Explorer is coming on and staying on as well as when the brakes are applied the vehicle also feels like it wants to go?
the abs light means you have a problem in your brake system it also means get it to a shop and have it fixed before the brakes fail and you are in a wreck as for feeling like it wants to go when the brakes are applied that in itself tells you there is a problem if the brakes are inadequate while stopped, how is it going to stop you in an emergency
Why does a car slide when braking?
A car slides when braking because the friction between the tires and the road decreases, causing the tires to lose grip and skid. This can happen if the brakes are applied too forcefully or if the road surface is slippery.
Do you need to reset your antilock brakes after you have applied the brakes hard?
Hey Brad No, They should be ok. GoodluckJOe
How far can a tractor trailer stop at 55mph?
Loaded, between 250 and 300 feet, if the brakes are cool before being applied. With brakes already hot, it may take up to twice that distance. Keep this in mind before you decide to cut directly in front of one.
How does braking affect acceleration in a moving vehicle?
Braking in a moving vehicle decreases acceleration by reducing the speed of the vehicle. When the brakes are applied, friction between the brake pads and the wheels slows down the vehicle, causing a decrease in acceleration.
How do you test a slack adjuster?
Assuming we are talking about "S" cam air brakes on a truck, check the angle at the end of the slack adjuster to the actuator rod coming out of the air brake can when brakes are applied, it should be 90 degrees, if the slack adjuster is manual adjust it with the brakes not applied and then test again. If they are automatic slack adjusters and you do not have 90 degrees with brakes applied it is worn out or not installed correctly.
