You must know the length of a R.R. car. Time the trains cars as they pass from a given point to the next. Now you divide time into that length to get feet per second. Do the math to get miles per hour.
The motion of a train on a moving track depends on the reference frame you choose. In the train's frame of reference, it may appear stationary or moving at a constant speed. However, in an external, stationary frame of reference, the train would appear to be moving at a different velocity that combines the train's speed with the speed of the track.
the passenger will be at rest relative to the rear car of the train, as they are both moving at the same speed and direction.
The passengers reference point ! The passengers are moving at the same speed as the train.
Someone walking toward the back of the train would have a greater speed relative to you if you are stationary inside the train. This is because their speed would be the combination of their walking speed and the speed of the train moving forward.
If you see a clock on a very fast train moving by you, you would observe that the clock appears to be moving faster than normal due to the train's speed. This is because of the relative motion between you and the train.
Yes if the train is moving forward, you are moving at the train speed + walking speed relative to the tracks.

Relative motion. To talk about a train moving at a certain speed usually means that the train is moving at a certain speed relative to a stationary observer (relative to the ground). This however also means that a passenger traveling in said train would experience the ground (and every other stationary object) as the moving object. This is why a stationary train may seem to be moving to passengers of an already moving train.
Someone walking toward the back of the train would have a greater speed relative to you if you are stationary inside the train. This is because their speed would be the combination of their walking speed and the speed of the train moving forward.
Yes, average speed can be used to calculate the speed of an object moving at a constant speed. This is because the average speed over a whole journey for an object moving at a constant speed is the same as its actual speed.
A train 108 m long moving at a speed of 50 kmph crosses a train 112 m long coming from the opposite direction in 6 seconds. The speed of the second train is
In this case, your train is moving faster than the other train. Say you were to take a radar gun on the train, and measure the speed of the other train from your seat. It would read a much lower speed than if you were standing beside the tracks as the trains pass. While both trains are moving, the other train is moving slower relative to you. Thus, it will seem that the train is moving backward, assuming that you take the speed from your seat.
If you see a clock on a very fast train moving by you, you would observe that the clock appears to be moving faster than normal due to the train's speed. This is because of the relative motion between you and the train.
No, stepping on the brakes of a moving train is an example of deceleration, as it is the action of slowing down or reducing the speed of the train. Acceleration refers to an increase in speed or velocity.
