We will speak in terms of relative speeds and distances: the locomotive in front will be presumed stationary, and the train behind is approaching from a distance of 676km at 132kmh-1. This, if you like, is the situation as observed by the driver of the slower locomotive. The train must come to rest after 676km. If it decelerates steadily from 132kmh-1, then its average speed over this distance will be 66kmh-1. Thus the time taken to deceletrate is 676km/66kmh-1 = 10.242h The deceleration is therefore 132kmh-1/10.242h = 12.89kmh-2 (two decimal places) This is the minimum deceleration, because it ensures that the train stops gaining on the locomotive only at the last possible moment, when the two are adjacent. There are plenty of prefabricated equations for calculations of this kind, but sometimes it is better just to have a fiddle around.
What else can I help you with?
What is the relationship between skid length and the initial velocity of a car help answer this theorotically not in formula thnkx?
In a car the maximum acceleration (deceleration) caused by breaks is about 1 g. Thus the faster the initial speed, then the greater the time AND distance needed to come to a stop will be required.
What is the force required to cause a car mass of 1000 kg to come to a stop in 40s if it is initially traveling at 20ms?
To calculate the force required to bring the car to a stop, we can use the equation F = ma, where F is the force, m is the mass of the car (1000 kg), and a is the acceleration. The deceleration in this case is the change in velocity divided by the time taken, so a = (0 - 20) / 40 = -0.5 m/s^2. Plugging in the values, we get F = 1000 kg * (-0.5 m/s^2) = -500 N. The negative sign indicates that the force should act in the direction opposite to the initial motion of the car.
A car of mass 900 kg moves at 10ms what is the braking force required to stop the car in a time of 5 seconds?
f=m*a a=m/s^2 so a = 72m/s * 4 s = 288 m/s^2 since you are breaking that means you are de-accelerating making the naswer be -288m/s^2 f = m* a substitute f= 8500kg * -288m/s^2 f= -2448000 N or -2.448 x 10 ^ 6
A 2.7-kg box is released on a horizontal surface with an initial speed of 2.9 ms It moves on the surface with a deceleration of 0.27 ms2 Calculate the kinetic friction force on the box?
The force of kinetic friction can be calculated using the formula: force of kinetic friction = mass * acceleration. The acceleration in this case is the deceleration, so the force of kinetic friction = 2.7 kg * 0.27 m/s^2. Therefore, the kinetic friction force on the box is 0.729 N.
What is the smallest height needed to make a wave?
The smallest height required to make a wave is typically determined by the speed of the wave (which depends on the medium it's traveling through) and the wavelength. In general, waves with smaller amplitudes may still exist, but they might not be easily detectable or have significant energy.
Actions that may be required when you execute a decision include?
Acceleration, deceleration and Steering
What time and distance is required at constant deceleration from 1037.978 MPH to 0 MPH?
The time depends on the deceleration... If you choose a time, draw it a graph, the area under the line is distance traveled and well the time is the time you choose. Or if deceleration is -1037.978 miles per second per second the time is 1 second.
Is a notarized letter required for traveling with a minor"?
Yes, a notarized letter is often required when traveling with a minor to prove consent from the child's parents or legal guardians.
Which of these is required for everyone traveling outside of the US?
Passport
Do you need a passport for traveling to the Cayman Islands?
Yes, a valid passport is required for traveling to the Cayman Islands.
What documents are required for traveling with children?
When traveling with children, you typically need their passports, birth certificates, and any required visas. It's also a good idea to carry a consent letter if only one parent is traveling with the child.
Is traveling required for the jos cartoonist?
I think you will need to travel
Are UK transit visas required for green card holders traveling through the UK"?
Yes, UK transit visas are required for green card holders traveling through the UK.
Is a notarized letter required for a child traveling with only one parent"?
Yes, a notarized letter is typically required for a child traveling with only one parent to provide consent for the trip.
What is the purpose of locomotion?
The purpose of a train's locomotive is to provide sufficient power to move the train and it's passengers or cargo to it's required destination.
Do you need a visa for Austria"?
Yes, a visa is required for traveling to Austria.
What muscles are prone to injury because they have less support from larger muscles and are required for deceleration of the arm during any throwing or swinging movements?
deltoids.
