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.

If a train is speeding down a railroad track at a speed of 50 miles per hour. From whose reference point is the train not moving?
The passengers reference point ! The passengers are moving at the same speed as the train.
A passenger in the rear car of a train moving at a steady speed is at rest relative to?
The train.
how would an observer on train a witch is moving at nearly the speed of light view o'clock on train be which is moving at the same speed and in the same direction?
The clock on train B would appear to be the same width and to run at the same rate
How do you apply the concept of momentum to compare the mass and velocity of a slow moving train and of a high-speed bullet?
The slow moving train has a much higher mass than the high-speed bullet, but the bullet has a faster velocity than the slow moving train so their momentum is the same.
If a person in a train moving at high speeds threw a ball straight into the air would the ball continue at the same speed as the thrower or would it travel a different speed?
Assuming the train continues moving at constant speed, the ball would travel at the same speed as the thrower.
If you are moving to the front of a moving train are you moving faster than the train relative to the earth?
Yes if the train is moving forward, you are moving at the train speed + walking speed relative to the tracks.
Why does one train seem to move when other train is already moving?
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.

Can you use average speed to calculate the speed of an object that is moving at a constant speed?
Yes. If an object is moving at a constant speed the average speed and the constant speed are the same.
A train 108 m long moving at a speed of 50 kmph crosses a train 112 m long coming from the opposite?
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

You are riding on a train going north and you see a car traveling north parallel to the train yet the car seems to be going backward can someone explain this?
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.
How do you apply the concept of momentum to compare the mass and velocity of a slow moving train and of a high-speed bullet?
The slow moving train has a much higher mass than the high-speed bullet, but the bullet has a faster velocity than the slow moving train so their momentum is the same.
How do you calculate distance from speed of vehicle?
Speed X journey time. (Time actually moving).
If a person in a train moving at high speeds threw a ball straight into the air would the ball continue at the same speed as the thrower or would it travel a different speed?
Assuming the train continues moving at constant speed, the ball would travel at the same speed as the thrower.
What is the speed of a train that is moving 500 km in 5 hrs?
100 kph
