Urgent need help 100 points Suppose that scientists observe violent gas eruptions on a planet with an acceleration due to gravity of 3.6 m/s2.
The jets throw sand and dust about 75 m
above the surface.

What is the speed i
of the material just as it leaves the surface?

Scientists estimate that the jets originate as high‑pressure gas speeds through vents just below ground at about 150 km/h.
How much energy per kilogram of material does the jet lose to nonconservative forces as the high‑speed matter forces its way to the surface and into the air?
