Get a CRC handbook. These questions have been settled at this level for
several hundred years. The equations that you are using do not correct
for atmospheric friction. Atmospheric friction is not relevant to slow moving
objects, but is highly relevant to objects in this speed range...approximately
681 miles per hour...close to the speed of sound at sea level...above it
at higher altitudes. Without atmosphere considerations, 999.5 fps is not an
excessive speed. Look up in the sky some night and when you see a
streak of light, you will have an answer to that question. Most of the math
at this level was developed to work out the science of ballistics. Last time
I looked, the ballistic tables were available from the US Naval Observatory
site.
