In May 1990 the French TGV train traveled the distance from Paris to Lille, France (127 miles) in 0.819 hours. What was the speed of the TGV in m/s

The TGV train has a speed of 69.306 meters per second.

Let suppose that TGV train is travelling at uniform velocity, then we can be calculated its speed by means of the following kinematic equation:

(1)

Where:

Now we proceed to convert both distance and time in terms of fundamental units:

Distance:

Time:

If we know that and , then the speed of the TGV train is:

The TGV train has a speed of 69.306 meters per second.

We kindly invite you to check this question about kinematics: link

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate
