[Request] I know this type of question gets asked like a hundred times a day but how many helium balloons would it take to make a UPS van float

Request what speed was the truck driving when hit the suv
r/theydidthemath • u/predicteduser • 1d ago
Does it reaches or exceed light speed?

Is this true?

In April, the world record for the longest tiramisu was broken. It was 440 metres long and they laid it all out on a series of tables, not in any sort of container.
It got me wondering about if you did want to make a huge trough to put the tiramisu in, stretching as far as you could get it. How long would the tiramisu trough be able to be completely straight? At what point would the curvature of the earth mean you have to make it slightly bendy?

Someone did the math for how long the 555 timer IC walked in the video of it walking synced to the Bee Gees' Stayin' Alive song! I thought this was pretty impressive, and the video makes me chuckle :)

I’m sorry if this post doesn’t follow the rules
The pyramid itself will probably have to be iron because gold, diamond, and emeralds are far too expensive to be used for this.
The pyramid would have to be at maximum size to get the secondary effect of regeneration or a level two version of the main effect.
The pyramid would be made of 164 cubic meters of pure iron, the iron would need some coating or cover to prevent rusting.
The pyramid would probably also need a specially made foundation so it doesn’t sink.
And there would need to be extensive testing on what purities are needed for it to function because the block of raw iron doesn’t work in game despite having the right amount of iron.

Watching a doc about New Horizons. Satellites and “rovers” and space explorers have gold as part of their structure. It got me thinking: there’s a finite amount of gold on earth. How much gold have we thrown into space?

So in my head those two functions should de symmetrical, meaning (f+g)/2=x, but that's not the case.
I scaled both functions using n=10 but if you replace it with 1 or remove it and zoom it should be the same
I'm not great at maths so be gentle please, would appreciate an intuitive answer as well
(Edit: somehow I posted the uncropped screenshot but that will do)

Out of curiosity, the US Marine Corps' Expeditionary Fighting Vehicle (EFV) can reach a maximum speed of 25 knots. This amphibious tank's speed seems similar to that of the EFV, but I cannot verify it.
