I see his skin was pierced, so I’ll up the estimate to something below 3000 feet per second or something below 1000 mph.
At 30,000 mph his hand would have exploded, and was was left of the meteorite would have been 20 feet under the ground.
Along with everthing around him. The expanding air and shockwave would have ripped him to shreds. It is impossible for an object of that mass to go that fast through our atmosphere without propulsion.
