: I did the following to figure out how many pushups the strongest man on earth can do in 15 seconds. I really have no knowledge of physics, and i got the formulas off several websites. I want to know how close I actually am: : The strongset man on earth has a power of 1126.71 watts. He weighs 59.8739 kg. The pushups he is doing are 0.3048 meters each. I used the following formulas: : 1kg = 9.8 N : Work = force * displacement : Power = work / time : Power = (force * displacement) / time : time-to-fall = SQRT (2 * Heigh-of-fall / g) : Power = (586.764 N * 0.3048 m) / 15 = 55448.327 : pushups-per-15-seconds (without any time to fall at all) = power / force = 55448.327 / 586.764 = 94.4985 pushups : each pushup takes (15 / 94.4985) seconds = 0.1587 seconds : time-to-fall = sqrt ( 2 * 0.3048 / 9.8 ) = 0.24941 seconds : Pushup + time-to-fall = 0.4081 seconds : 15 / 0.4081 = *36.7557 pushups per second*
