in case the speed they are traveling causes them to collide or rock against each other and scrape
If two trains are passing each other the relative speed can be found by adding the individual speeds of the two trains. This applies if the trains are passing each other in opposite directions. Should one be passing the other and both be moving in the same direction, the difference of the individual speeds would be the relative speed of the trains.
If two trains on different tracks are moving at the same speed, they will pass each other. However, if they are moving in opposite directions on parallel tracks, it may appear that they are not passing each other since their relative speed is zero. This is because their velocities relative to each other cancel out.
The change in speed each second when the ball is tossed upward will decrease by 9.8 m/s each second due to gravity until it reaches its highest point and starts falling back down. On the way down, the speed will increase by 9.8 m/s each second as gravity accelerates the ball towards the ground.
Oh, isn't that an interesting scenario! Even though the cars are both going 40 mph, they are moving towards each other, so we can say they have a combined speed of 80 mph relative to each other. Each car is still going 40 mph in its own direction, but when you look at them coming towards each other, it's like they're going 80 mph together.
The wave speed is equal to the frequency multiplied by the wavelength. In this case, since the wave vibrates up and down twice per second (frequency = 2 Hz) and travels a distance of M each second, its wave speed would be 2M/s.

The trains will collide in one hour. The answer is 8 miles.
By definition, if they are parallel to each other, they will never collide, so the chance is zero.
The pressure between the trains increases momentarily as they pass each other due to the changes in airflow. This can create a temporary increase in pressure on the outside of the trains.
Its not the speed over the roadbed that counts (all 3 are about the same) but the fact that unit trains do not need to be classified at each intermediary yard that makes them the "fastest".
50 Km/h, obviously.
they take turns running trains on each other
the rail road signal works in two ways to which it shows if a train is coming and also it show the speed of trains so that the captain could know to which speed they would be heading when the cross past each other
There is addition of the speed.
Because they would hit each other and many people would die...
No, but they are just a short walk from each other
