These are well supersonic in this video, and likely still hypersonic (they were definitely hypersonic at the initial stages of re-entry). Compare how fast these look compared to airliners, which are going 80+ percent of the speed of sound and look like they're crawling by comparison.
Impacts were far as hell. Have you ever seen a plane high up in the sky? Sometimes they look so slow they're almost stationary. And even those are faster than Mach 0.5
Incorrect. Balistic Missiles are also subsonic in the terminal phase due to targeting. Notice there is no sonic boom (if they were faster than mach 1, there would). All Balistic Missiles slow down before impact. That is why it is actually possible to take them down
The whole idea to create hypersonic missiles, like we have been seeying from Russia, is to try and make them faster in all phases, but they ALSO need to slow down to fine-target at the end.
There aren't sonic booms in this video. We'd hear both the boom and the detonation blasts if they were super or hypersonic. We're only hearing the detonation. They aren't mach 1+

Gives the average person a good idea of the speeds we are talking about (Mach 5+) when talking about ballistic missiles in their terminal faze.
And hopefully a better idea of why ballistic missiles are a pain to intercept.
