Need guidance for these calcs

[Shadowslash125]

Amateur Calcer here returning to you live in need of some help.
First off, I need guidance in calcing the speed of this feat, where this Rider guy shoots from far away, and the shot impact might be less than a second (or a second). The problem is that idk how to calc the distance between Geats and the gigantic battleship.
Another one is this feat right here. Mainly the uneven shape to be identified so that I can calc the volume that was destroyed.
Last but not least is this feat, for calcing the LS required to kick this can filled with liquid to the sky, and with good force when kicked elsewhere.

Angsize Geats Distance from screen, then Angsize the ship distance from screen. Then you do this: (Distance the ship was away from Geats - Distance Geats was away from Screen)

Ofc, to get a result in meters, you'll need to px size Geats, then (assuming he's the height of an average male which is 1.72m unless u got an official height scan), u divide 1.72 by the px size of Geats to find how many meters there is in 1px

Example:
Geats = 1.72m = 500px

1.72/500 = 0.00344

So 1px= 0.00344m

Looks like a triangle

Not sure about this one but you can look up for other similar calcs on the website that has been accepted and copy their method

Looks like a triangle

The inner parts of the triangle are pretty jagged and vary in depth, That's what I was asking about (I clarified wrongly).

I think you could treat it as an ellipsoid and calc it like here
