I need help

No.14279909 ViewReplyOriginalReport
I'm having a lot of trouble with this question, i can't think of where to start and i would really appreciate some help.

Consider an ideal spring-mass system. A spring obeying Hooke's law can be deformed only along a given direction (X axis) has one of its ends fixed and the other free, where a mass m is attached and can move. Use a coordinate system where the mass coordinate also indicates the spring deformation. (1) In a general way, describe in this coordinate system all the pertinent vectors just after the mass starts moving. (2) Use Newton's second law to determine the trajectory of mass m after it is released from rest with the spring stretched (positive strain) by A0 units of length and comment on your results. (3) Calculate the mechanical energy, as well as each of its parts, explicitly as a function of time and comment on your results. (4) Qualitatively, comment on the modifications introduced by placing this spring-mass system in a fluid, such as the atmosphere, for example.

limited numbers is a sign of the matrix?
why do we only have 0
-9 digits? and then there are repetitions of the same numbers

means the matrix is limited to these digits?

and why in nature in most of both sides ? is this binary code?

Alien Civilizations

It is pure insanity wanting to contact an Alien Civilization, broadcasting your position beyond insane.

Alien fetishists are insane and a threat to us all.

>b-b-b- I have to know if we are not alone
Why ? Literally no on is interested in this answer except other alien fetishists.

>b-b-b- aliens and shit dude.
Congratulations now you have an alien civilization who is more technologically advanced at our doorstep. Get ready to get fucked hard.

>b-b-b- why are you assuming they will be hostile ?
Why are you not ? What you think they show up here and will simply give us tech without any bullshit ?

We are talking about aliens who are totally different and nowhere in history did contact between civilizations end up beneficial to the less primitives.

Like Columbus to the Indians.

>b-b-b- my crazy magic that can detect us already
1) it magic BS that can not work
2) Then why are you insisting on shouting into space so they can detect us ?

>b-b-b- the distance between starts it to great for travel.

What if it is not ? Want to see what happens if they warp jump here ?

So if everything we see and interact with is just an image projected in our head combined with all of our senses. What does the world outside of our head actually look like?
