Universal causality propagation rate

>2020
>people still falling for this
It's fake you pozzed newfags

makes me wonder if the student asked someone for help and the person gave them the true equation to solve this problem but the teacher is too dumb to understand the equation or even how to round up

I haven't done anything physics related in a decade give me a break

He's either incredibly based or aggressively insufferable. There is no in between with this specific type of person.

what the fuck is a mile?

this is so god damned fake lol, besides the fact that it's immediately obviously fake, you would never have a physics problem like that on the same HW as the following problem.
If you think that isn't a physics problem because it's so easy and you think that elementary schoolers intuitevely understand reference frames you have autism

~16000 foreskins laid side by side

it's not a physics problem though retard

someone interested in math/physics would know about the whole universal speed limit thing. but we can't have people actually interested in stuff. I'd heard about it in third grade, and had I not been surrounded by retards (or had internet access) I would've found that equation as well, and tried to impress/shame the teacher for being a retard.

This. You dont teach the concept of physics the same year youre covering basic addition and subtraction.

oof, he's flexing

the data given in the question provides only 1 significant figure so the answer is indeed 80mi/h

How would a kid understand that you have to add the two numbers together? It only seems obvious to you because you already understand the basic principles of physics

uh, yes, there are routinely "simple" questions that just want you to go "x + y = answer" but if you know anything, they'd be almost impossible to answer. Like trying to evaluate the curvature of the earth to calculate how far two trains are from each other if they traveled in opposite directions.

>mph
Jesus Christ how horrifying

Basic kinematics are absolutely physics

because he didn't show his work.

...AND THAT LITTLE BOY'S NAME...

the first time I got the stupid "two trains leave boston" question was in like 2nd grade and I asked the teacher how I was supposed to calculate the curvature of the earth and if I needed a map of boston to see which lines they used.

only the busdriver would know the speed of the bus, because only he has access to the speedometer
so the question becomes unanswerable

imagine using fucking miles feets and other retarded shit

To everyone saying this is fake, here's the story and it would actually make a good movie:
>High School in South Africa in 1992
>New wave of teachers come in to replace ones that have left for some reason
>They have to lower standards for entry since there isn't the workforce
>One new teacher is for physics
>Teacher sets the exam but just finds questions out of some book
>White kid makes understandable mistake
>Black kids all get 100% and teacher turns out to be illiterate
>Society collpases

This just pisses me off.

Is this really true though? Isn't the ball still traveling 30km including the speed of light thing? I mean it's basically the same as if a person in a bus is walking forwards he isn't really moving faster than the bus. I guess the clue here is that the observer sees it as if the ball was traveling faster, but it's not really is it? I mean what would happen if the ball hits the observer in the face? Will it be an 80 or a 30 mph hit in the face?

> I mean it's basically the same as if a person in a bus is walking forwards he isn't really moving faster than the bus.
what? yes he is. He inherits the bus' velocity and adds on his own...

Are you ok?

Pretty based, not all multiplication is commutative.

Are teachers worthy of admiration for basically babysitting?

>but it's not really is it?
Yes, it really is.

Yes, kids (especially blacks) are nightmares.

this feels fake because nobody calls that an array

even the try hard answer is wrong because 50 and 30mph are in a rotating reference frame. they need to be converted to an inertial reference frame

wrong

half wrong

correct

someone wasn't paying attention in school

It's undeniably wrong though. The guy wrote out 6 units past the decimal resolution. You cant have a solution that is more precise in resolution than the data used.
>you cant use a kitchen scale to measure atomic weight
The answer is 80.

Its not right. Hes not taking earths gravity in effect for starters.

No one cares nerd.

chuck

because the answer is actually 79.999990447999409519203497953365. he's way off.

If this kid were in my class I would've given him recess detention for showing off. Fucking hate these kids with NASA parents who make their science fair projects for them.

>Fucking hate these kids with NASA parents who make their science fair projects for them.
t.lost science fair 20 years ago to chad blue blood kids parents

e=mc^2
the amount of energy in something is equal to its mass multiplied by the speed of light squared.

the teacher was surely a city slicker

Wait, why is it actually slower?
Why does the static reference frame mean it's going slightly slower?

Because the faster you go the slower you go

Hes right lol.

You can filter out psuedo physic idiots. Look at this thread.

Watch. Everything is traveling at the speed of light, either its through time or space or a combination. Go faster through space, you travel through time slower, and vice versa

Its all about energy density at a moment and place in spacetime.

The majority of teachers in the USA are this incompetent. The entirety of mathematics before high school could be taught to a 6 year old child in a month, which is what my Russian parents did. My first grade teacher didn't know what negative numbers were, which explains why Americans go into $100k debt to get a degree in English or something else pointless. They literally do not understand debt.

Okay thanks.
