Calc for a building fragment hitting someone from a few feet high?

[Naito-desu]

I have other perspective pics for the length and the width but I'm just looking for how to get the velocity of the thing falling, since it didn't really fall far enough to consider terminal velocity

Calculate the mass of the object in question, calculate the height and then use the Splat calculator.

Or, just use on-screen KE.

Wait, is that what I think it is? Is this the infamous catapult reflecting feat in For Honor that Grath was telling me about? Can I get a video of this feat?

 

[Naito-desu]

Oh no, it's an environmental hazard in the fight against Apollyon. Catapult reflecting feat is a different beast entirely since FH heroes can actually deflect things like fire bombs and traps and whatnot, likely in-game jank as usual

Oh, it's in the fight against Apollyon then. Aight, lemme see what I can dig up.

Aight so basically all you need to do is figure out the height from which this thing falls and if possible, calculate how long it takes to reach the bottom, from there on you can calc the KE of the stuff. Or if you wanna take the easy way, use the Splat Calculator.

But I'd highly recommend taking the KE route since the timeframe should be calc'able here.

Watching the fall, it's about 1-2 seconds when the indicators show/rumbling happens. The Orochi is female in my reference picture, so assume an average height of 160cm of a Japanese woman.

 

[Naito-desu]

Orochi is 174px while height of fall is 796, so 796/174 = 4.57471264368 x 160cm = 731.954 cm or 7.32 meters

So I have the time of the fall and the height, all I need is the mass then what formula is needed?

Use the usual mass-density volume calculator to find mass. Mass= Density * Volume

 

[Naito-desu]

So after that KE = mass * distance (7.32meters)/time (1.5 seconds) ?

 

[Naito-desu]

Actually scratch the 1.5 seconds, the indicators aren''t accurate at representing the fall

Alright so here's the tally for the numerous methods I tried:

Joules on impact: The rock fragments upon impact, so that would be the most simple avenue of calculation for impact power. The approx. volume of the falling column was 5 502 160.5vcm^3, assuming it was limestone, the fragmentation value would be 10j/cc, which makes the energy about 55 mega joules or Small Building Level

Joules from the fall itself: The timing of the indicators doesn't seem to be accurate, and the rocks actually fall at different rates. It might be artificially slowed as well, so I'm trusting free fall calcs, and they say about 1 million joules; But if we go on the highest end of the falling times, about 500+k joules for the falling rocks

Free-fall is the most accurate for this method then. Use the splat calculator.

Once you're done, put it up on a blog for people to evaluate.

Alright, the blog has been created
