Here is a CV measurement of the boulder "feat".https://comicvine.gamespot.com/forums/gen-discussion-1/mcu-kurse-boulder-feat-1827540/?page=1
They place the weight at around 300-500 tons and the force of the toss at 1.02 Gigajoules. I'm a bit skeptical with their rest of their math but they didn't get too far off from where I was with the weight when I did a calculation some time back w/c came up with 211 tons.
The Boulder is approximately an ellipsoid. V=4/3pi*a*b*c
Also Kurse is standing at most 2 meters tall (not taller), especially since he's not standing completely straight up.
a=3m, b=2m, and c=2m
V=50m^3.
As a lower estimate D=2tons/m^3
M=D*V= 2×50= 100ton.
The first problem I have is that the Boulder appeared to be composed of much dirt (or something even less dense than rock). The material appears very soft. If this is the case then then it would be somewhere between 10—70tons.
The second problem is the Boulder is a much smaller size when Kurse breaks it off and lifts it from the grounded part. It becomes bigger in the next scene. The calculations come from the scene where it is shown LARGEST so this isn't really a problem. Just wanted to point it out.
The third problem is the calculation of the throw. Kurse uses about 1 meter of distance (bending knees and extending arms) to accelerate the Boulder from 0 to about 74ft/s (23m/s). This give an acceleration of 265m/s^2.
Force = MA = 270ton minimum.
