Question 1153455
.
<pre>

In my post, I only want to explain to the visitor, that the given equation DOES NOT describe the flight of a real rocket.


It describe the flight of a PROJECTILE, i.e. an object launched with the initial velocity of 217 m/s,


but then falling freely under the Earth's gravitation force.


The drag force, which provides vertical acceleration of a real rocket,  ABSENTS in the given equation (!)


So, it is not a real rocket (!) (!)


Such object has a common name "a projectile" in Physics.
