If a train is stopped suddenly then it's acceleration will be zero or it's velocity will be zero?

As it slows it's acceleration will be negative, deceleration is negative acceleration. During the slow down the velocity will drop. Once at rest both acceleration and velocity will be zero.

How can you tell if a train is going at a constant velocity or accelerating?
If you are inside the train then you can use a device called an accelerometer. If you are outside the train then you can time how long it takes the train to travel two successive distances, and use the SUVAT equations to determine it speed over each of the distances.
Why person jumping out of a speeding train fall forward?
The velocity of the person is the velocity of the speeding train plus the velocity of the jump out. this gives a resultant velocity with a forward component in the direction of the train's motion.
How does friction affect the velocity of a train?
friction will act in the opposite direction to the propulsion force driving the train. so it will cause a resistance and so limit the velocity
Is stepping on the brakes of a moving train an example of acceleration?
Is stepping on the brakes of a car acceleration. That would be deceleration.
What is steady velocity?
Steady velocity means keeping the same speed. Like in "between the stations, the train maintained a steady velocity".
A train travels from one city to another its initial velocity is lower then its final velocity?
Positive acceleration.
What is the maximum acceleration of a train travelling at 90 miles per hour?
The speed or velocity of a train has no bearing on its acceleration.

Can a body at rest have an accleration?
acceleration is a relative quantity . state of rest or motion is also relative . if two body is in rest or moving with same velocity and having same acceleration then one is in state of rest with respect to other . suppose a person sitting in a train then he is in rest with respect to train but he is moving with the acceleration of train with respect to the ground.
If a bird hovers inside a train whilst that train is moving then presumably it is travelling at the same speed as the train Why is this and why is it not thown to the back of a carriage?
What pushes us back is a change in velocity (i.e., an acceleration), not the velocity itself. You might as well say that the train is stationary, and that planet Earth is moving under the train. In outer space, there is no fixed reference point; and it doesn't make sense to speak of the "real" velocity. A velocity must always be indicated with relationship to some reference point. Using the Earth as a reference point is convenient, but it isn't the only option.What pushes us back is a change in velocity (i.e., an acceleration), not the velocity itself.

What is the acceleration of any object moving at constant velocity?
0. Doesn't matter what unit it is. If it's moving at a constant velocity, not changing its speed (either positively or negatively), it's not accelerating, right? So its acceleration is 0. However, we must remember to always define; 'with respect to what'. Velocity is a relative concept. i.e. If you are sitting at rest or walking with constant velocity on a train, yet the train is accelerating, are you accelerating? wrt the train - the answer is no. wrt the embankment - the answer is yes. The answer then relates to something else, which is your own 'centre of mass' inertial rest frame. (i.e. you can 'feel' acceleration). So wrt your 'previous' state. This is normally quite poorly understood.
How do you make a complaint to corporate headquarters for Days Inn motels?
a train staring from rest acquires a velocity of 40m/s in 10sec.what is its acceleration
What is the final velocity of a train that starts at rest and accelerates for 15.0 seconds at an average acceleration of 2.40 meter per second squared?
Unknown: final velocity, vfKnown:initial velocity, vi = 0m/stime, t = 15.0saverage acceleration, a = 2.40m/s2Equation:vf = vi + atSolution:vf = 0 + 2.40m/s2 x 15.0s = 36.0m/s

The velocity of the person is the velocity of the speeding train plus the velocity of the jump out. this gives a resultant velocity with a forward component in the direction of the train's motion.
A train starting from rest attains a velocity of 72Km hr in 5 minutes. Assuming that the acceleration is uniform what is the distance travel by train while attained the velocity?
As the acceleration is uniform, the train has an average speed that is half the difference between the start and final velocities, which in this case is half the final velocity. 1 hr = 60 min 1 km/h = 1 km ÷ 1 hr = km ÷ 60 min = 1/60 km/min Distance = velocity × time = (½ × 72 × 1/60 km/min) × (5 min) = 36/60 × 5 km = 3 km
Compare the tension of a train with constant speed and acceleration?
Unless the train is in a curve, you cannot have constant speed and constant acceleration. You either have constant speed and zero acceleration, or you have changing speed and constant acceleration. Please restate the question.
In the book night Where did the train stop?
The train stopped in "Aushwiz."
