Hell, it's the 21st century now, I'll use Google: "700 foot-pounds = 9.49072564 × 109 ergs" Somehow I don't think that helps. Are you happy now?
OK, I guess I wouldn't mind having dropped on my head a 4.4 pound drone traveling, hmm, approximately: sqrt(2gdistance) = Sqrt(232.3(400 feet)) = 160 f.p.s. with about 160 fps * 4.4lbs = 700 ft-lb of energy !!! Well,…
