The
Soyuz-U launch vehicle was an improved version of the original
Soyuz rocket. Soyuz-U was part of the
R-7 family of rockets based on the
R-7 Semyorka missile.

As you can see, even for liqued fuel, 5km/ second speed is cool.
I think SRBMs reach Mach 20 speed when they fall from space to earth thanks to gravity. They reach high speed in last stage , they don't reach high speed in first stage.
When in space and no more
thrust is provided, the missile enters free-flight. In order to cover large distances, ballistic missiles are usually launched into a high
sub-orbital spaceflight; for intercontinental missiles, the highest altitude (
apogee) reached during free-flight is about 1,200 kilometers (750 mi).
According the video:
T19:speed Mach1; 1100feet per second(335m/second);8300 feet altitude.
T39: speed Mach3;38000 feet altitude.
T+45:second roll maneuver 50000 feet altitude.
I wasnt able to understand further stages
There was wriiteen 90 miles at 300000feet??
Yani fuzenin gittigi yol aslinda 10bin km degil.
Ornegin Hindistan Shourya fuzesi 3- 5 dakikada 200km yukseklige cikiyor, 100km de uzayda da yol yapiyor, sonra uzaydan yerzune 200km dusuyor. Toplamda gidilen yol 500km filan, bu 200km yukseklige cikmak 180 saniyesini aliyor ,ve bu da yeryuznde 1500km lik bir menzile denk geliyor yanlis mi anladim? Turkiyenin muhtemel uzun menzilli balistik fuzeside boyle bir sey olacak.
Bora 300kmlik menzile sahip, demekki 60-70 km apogee yapiyor sonra yine dususe geciyor.
Minuteman'in yakit kullanarak yaptigi toplam yol 1200km filanmis. sonrasindada 1200km serbest dusus. Toplam kateettigi yol en fazla 2500km. Yeryuzunde 10bin kmlik bir mesafeye denk geliyor.
Toplam safha 2000 saniye 35 dakika filan , yukselme 320saniye en yavas safha.
