[Off-Site] Yik Yak user asks an 'impossible' answer, gets a quick result

Bad example of the impossible questions, given the sun part works perfectly without 'maws' and 'das'.

One of the examples we used where I live was 'A train is going east-west at 100km/h, the weather is stormy. Calculate the weight of the train'

That's not at all how math exams be...

They don't think it be like it is, but it do.

You dont know the standard constant for train and storm weight?!

But of course I do!


What's up with the image quality, here?

Well, it sucks.

37.4mm KM.

What is going on here. What is this unit even supposed to be? milli milli kilo meter?

There is nothing impressive about that math. It literally took half a second for me to type 1/47 into my calculator.

If it's following a line of latitude the centrifugal acceleration would affect (minutely) its normal force against a scale.

If the weather is stormy then that's a low pressure system, meaning the air is less dense and is applying less of a gravitational pull upwards than it normally does.

Storms also have a lot of water vapor which would increase the upwards gravitational pull.

I'm going to go with "the train would be measured as weighing less than it would in clear weather at rest"

Another case solved, thanks to you, Detective.

Solid work!

The minute amount of rain that would collect on the train would increase the weight more than your 3 listed factors combined son.

=heavier train bruh

You do realize 1AU is the distance from our earth to the sun

Isn't it just 1au/47? Why .25AU

For most of my physics and engineering classes, it actually is a reasonably accurate caricature, though I do think that the person posting it attempted and failed at giving an impossible problem.

Information that isn't useful mixed in with information that is, and oftentimes there's a known quantity important to the problem that needs to be looked up or remembered.

That's not a constant.

Maybe it's millimeter Kelvin Megas?

No, it's mm * KM, which comes out to m2. Not sure why we're measuring area though...

How so? 1/47 is .022112766. An Au is 149,597,871 kilometers. divided by 47 is 3,182,933.43. I'm not a math guy but this seems pretty simple.
