I loved this post, but I have to be a worthless pedant.
If you drop a ball off a 120-m tall building, you expect impact in t=sqrt(2H/g)=~5 s. But that would be when the second-hand is on the 1 numeral.
Heh. I got this right originally, then reread it just recently while working on the book, saw what I thought was an error (1 numeral? just one second? why?) and “fixed” it.
