For the purposes of my story, seen here someone who went through a similar procedure involving parallel dimensions (see here), becomes nearly indestructible , invulnerable to damage related to excessive heat and fully capable of moving, reacting to stimuli and processing information at the speed of Mach 50 (61740 km/h or 17150 m/s). However, he is still subjected to the forces of air resistance and the consequences of moving at such speeds aren't mitigated or negated by any kind of external "magic" agent. In this situation, I'd like to know what exactly would happen to his environment if he moved at full speed.
In my first question regarding this topic, one of the answers spoke about causing sonic booms, shredding clothes of nearby humans and possibly causing the formation of plasma, but I couldn't find any source which gave me a more precise understanding of what would happen should a human-shaped object moved at speeds above the sound barrier, let alone at such a speed.
In a scenario in which the protagonist, weighting 70kg, being 2m tall and having a volume of approximately 0.062 cubic meters, travels in a straight line a distance of 17150 meters at his max speed of Mach 50 on anasphalt road (assume the road is fully contained within a plane horizontal to the ground) located at sea level (air density being approximately 1.2 kg per cubic meter). What exactly are the results of this human-shaped object (or approximately human shaped if that makes it easier to estimate) to his surroundings, especially regarding the sonic boom and the effects of said movement to the air around him?
-Assume the runner is indestructible, isn't touching the ground despite being infinitely close to it and/or is in a static position, should any of those assumptions help in a better estimate.
-While not necessarily the focus, a small description of how his movement would affect a human being wearing a tuxedo and an average 2 story building with normal glass windows, both at a 3 meter distance and perpendicular to his trajectory, would be greatly appreciated.
-if there's some kind of data lacking, please let me know, so that I may edit it in (I'm not sure exactly of what formula would render me the answer I want, of if there is such a formula).
