By that particular equation, a boeing 747 can hit 1300 mph (about double the true number) and sixth generation fighter jets can hit 2500 mph (about 1000 mph high). The equation performs best for needle-like rocket shapes with 1G or more of acceleration. It also claims that 10 cm per second squared acceleration can get you to 250 mph in atmosphere, and that's even more obviously wrong.


I would not use that acceleration equation for anything under 1G. I do have an alternate equation, which is to remove the square root, and replace the 2,500 mph with 1,500 mph if its plane like rather than rocket like (and with that kind of thrust, it needs to be to take off). So I've got the top speed for the plane at 150 mph for sea level air pressure.
