I believe it's People interacting. I hope i've helped you! (:
Here we can say that rate of flow must be constant
so here we will have

now we know that


now from above equation



so velocity will reduce by factor 0.14
You said that she's losing 1.9 m/s of her speed every second.
So it'll take
(6 m/s) / (1.9 m/s²) = 3.158 seconds (rounded)
to lose all of her initial speed, and stop.
Explanation:
It varies with altitude, but at sea level, it's 9.8 m/s².
Answer: The theory of Plate Tectonics is now widely accepted because there is sufficient proof to support it, and it is an important aspect of geology, oceanography, geophysics and even paleontology.
Explanation: In places where a plate faced resistance to its movement, it would fold upward and create mountains. Hope this helped! :)
