fine a weight estimate.
peakhumans pritty vage response.
also I would like one for both heights if you don't mind.
neglecting momentum, wind friction and other variables not including gravity, the 130 lbs would need an initial velocity of 13.39 m/s to reach a height of 30 feet. that means it would start with approximately 5289 joules of kinetic energy, and slow to a stop at the height of 30 feet, losing all of that energy. assuming an average press uses a speed of 1 m/s, approximately the length of an arm in one second, that same amount of kinetic energy would allow someone to press just over twenty-three thousand pounds.
i hope you're not alleging [sloppy] physics just proved wolverine to be an 11.5 tonner. i hope you can actually see the futility of using this as an argument.

I was just going to say "lots" but I like this answer better! 😄

What strength level would you be at to do the same with a car that weighs one and a half tons?
using the same formula, which still neglects friction and momentum etc, you'd need to be able to lift approx. 269 tons. of course, this implies that you can lift as much as you can throw, which isn't necessarily the case given the dynamics of both exercises, but it seems to be a principle people will apply when comparing strength feats and power levels.

With regard to the thread question, try this...
1. Determine how much weight you can military-press for a 1-rep max (let's say it's 100 pounds; I'd read somewhere once that this is about what the average man can press).
2. Take a 5-pound plate and toss it into the air next to an apartment building. Estimate how many stories high the plate went (let's say 2, so that's 20 ft).
3. 130 lbs div by 5 lbs = 26. Ie, you threw 1/26th the target weight 20 ft high, or 2/3s the target height (30 ft), with the strength to press 100 lbs.
4. 30 ft is 50% more than 20 ft, so you would need 50% more strength to get 5 lbs up to 30 ft, or the strength to press 150 lbs.
5. 5 lbs is 1/26 of 130 lbs, so you would need 26 x 150 lbs -- or the strength to press 3900 pounds (almost 2 tons) -- to toss 130 lbs 30 ft up (this is, of course, assuming all other variables, like air resistance, are unchanged). Based on #1, this would make you 39x stronger than the average man.

That is pretty good🙂
However something to keep in mind with the initial weight (100lbs), that the type of power displayed by throwing the weight isn't going to translate into direct power of the press, some physiological factors come into play. Which after reading alot of your posts you probably knew, it was a good read though Mindship, I love your math posts.

that's really speculative physics isn't it, on the assumption it goes two stories high, rather than on the necessary velocity needed to reach that height given the deceleration due to gravity?
In fact, consider the following: a World's Strongest Man competition recently held an event where contestants had to toss 60-pound kegs over a 14 ft wall. All else being equal, wouldn't physics dictate that to toss 130 lbs to 30 ft requires (roughly) 4x the energy (about 2x the weight to about 2x the height)?
Now any of these guys could probably military-press 400 pounds (they weigh around 300 lbs themselves -- and bodyweight is another factor we're "neglecting"😉. So to toss 130 lbs to 30 ft suggests, again, 4x that strength (or at least, 4x the energy), which means a strongman would have to be able to military-press 1600 pounds...less than half my original estimate. But that's why I say, go do an actual experiment with manageable poundages, see what you get, calculate from there.
