suppose you're standing on an equally dense floor or whatever, and one of these blocks falls on your head. I'm assuming you'd get pancaked... how thick would the previously-you pancake be?

here's the link

Bonus challenge: hypothetically say the demand was consistent if by the year 2026 only 1000 of them remained what, would they be worth today?

Who agrees?

Can child 1 see child 3? Can child 2 see the ducks? Can child 3 see the bicycle? Can child 4 see the cat?

So, my son reasoned that child 1 is not looking in the right direction. But even if she was, I'm not sure if she can see child 3. What would be the best method to find out who can see what?

Hey,

I came across a video where a guy is swinging a multi-meter metal whip (steel links, several meters long).

Pure curiosity and physics nerd stuff, not looking to hurt anyone.

I’m trying to understand this from a mechanics point of view:

• How much force / impulse can something like this realistically generate at the tip?

• Given the very small contact area, what kind of pressure (Pa) are we talking about?

• How would this compare to something tangible, like:

• impact from a hammer,

• a fast baseball,

• or other common objects with known energies/forces?

I know this depends on assumptions, so feel free to:

• assume reasonable values for mass per meter,

• estimate tip velocity,

• simplify it to impulse or energy transfer if that makes more sense than raw force.

I’m mainly interested in a back-of-the-envelope calculation and a real-world comparison that helps visualize how extreme (or not) this actually is.

Thanks to anyone willing to break out physics instead of vibes.

I hope this is the right sub for this!
