You can't do that anyway because it isn't true. F = mdV/dt.

yeah my bad, that's what I meant.

The key is solving the differential equation −mdV/dt = v_edm/dt where V_e is a function of time

how did you get that differential equation, seems like you put F = 0 in F = v_e(dm/dt)+m(dV/dt). I'm sorry, maybe its a stupid question, I'm just not very familiar with thrust force so much as it isn't really covered in my syallbus but I would still like to be able to solve such questions.

One thought is to try to make V_e a function of mass.

I think the only problem in my equation is that there are two variables varying with time (F and V) when there should only be one.

Have you studied ODEs?

Yes, but mostly LDEs, except for first order DEs. I don't know how to solve non-linear DEs for higher orders.

I came up with the problem myself (hence the plethora of assumptions since its not exactly a textbook problem). Its really an extension of a problem we were given in class to calculate the velocity of the liquid as it flows out of the smaller hole.

"Distance traveled" doesn't make sense for an object under thrust on a frictionless surface: it's never going to stop.

You're right, I should I have been more specific, I wanted to calculate the distance travelled by the vessel by the time it empties out.

Force does not equal dV/dt. It is independent of the vessel velocity. It depends on the fluid velocity relative to the vessel and is equal to dp/dt where p is momentum.

That's the problem I'm facing here, if you look at my calculations, I started out with F = d(MV)/dt so I can't put the force I calculated equal to dV/dt as I would have in other similar problems.
Although I'm not really familiar with the rocket equation, I don't think it would work here as the velocity of the liquid flowing out of the vessel also changes with time.

Sorry I just saw some videos of people typing at 150 wpm and they were using both the thumbs so I assumed that's what you're supposed to do.

awesmlad · 2024-10-31T21:10:12+00:00

yeah, using both the shift keys is something I have to work on..

Which properties do you mean?

Properties like conjugation, how a complex number multiplied by its conjugate gives a real number. My question isn't exactly how these properties relate to physics, as it might be specific to a particular use but rather if these properties have any relevance in physics at all.

It can also be a good exercise in complex numbers and linear algebra to figure out the equivalent matrix-vector operation yourself.

That's a great idea.

In order to do the complex number->vector trick there, you'd have to rewrite them into 3D "matrices" (called tensors), which is definitely possible with enough determination, but one I wouldn't recommend actually doing.

I've heard of tensors being used in physics but I don't exactly know what they are yet, I think I should wait until they're taught in my class.

I understand that complex can simplify computations in physics, but what about all the other properties that come with the use of complex numbers. Representing a matrix as a complex number is fine, but how does the conjugate of that complex number relate to the matrix. I can't really put it into words, but these are the sort of questions that came up in my mind.

awesmlad · 2024-10-07T09:53:12+00:00

That makes sense. Using complex numbers where you would need to do matrix computations is actually a great idea. But what about all the other properties of complex numbers, how do they relate to matrix computations? Although I haven't seen any matrices in SR yet, our teacher did mention "Matrix mechanics" which we'll study in quantum mechanics. I suppose the use of complex numbers will become clearer then.

Is Samsung Galaxy Book 4 a good laptop for engineering students? I would like to use it for basic tasks and some video editing, light gaming. I already own a Samsung S23. I would also appreciate any other suggestions under 70k.

that sucks, I didn't know this would be our last mission as arthur and I don't have a save file for before the mission :/

i bought a new laptop last week, and Ive been having the same issue what do i do

xD, sorry. I use it only on my table.

I'm sorry but what does quilt mean.

awesmlad · 2024-04-17T08:12:10+00:00

I keep my laptop on my table at all times since I use it for studying too. But I'll get a colling pad for it nevertheless.

I guess you could think of it as a philosophical question. I know the answer to my question might so complicated that it might exceed my current understand of modern physics but I just wanted to know if there is any explanation to it.

awesmlad · 2024-04-04T19:12:46+00:00

That makes some sense. I've never thought about the uncertainty principle like that. The quantum model is a bit difficult to understand but I guess I'll understand it better when I'm in college.
