Like.
@kuruman @PeroK @wrobel thanks to all of you -
PeroK replied to the thread Variable mass system : water sprayed into a moving container.Here's another way to look at it. There are no external forces on the large mass M. A small mass, m, is fired at a known speed (the...

PeroK replied to the thread Variable mass system : water sprayed into a moving container.... I don't see why analysing forces was necessary, if you are given everything you could possibly know about momentum!

As you have discovered, ChatGPT doesn't give a hoot whether you learn or not because it is constitutionally incapable of diagnosing...

PeroK reacted to Ibix's post in the thread I Synchronizing clocks in an inertial frame if light is anisotropic with Like.
I also agree. To call what you get with a homogenous but anisotropic two way speed a "simultaneity plane" you need to require that...

PeroK replied to the thread Variable mass system : water sprayed into a moving container.Okay, but that was my first step. That leads directly to a differential equation: $$\frac{d v}{dt} = \frac 1 {M(t)}k(u-v)$$where ##k =...

PeroK replied to the thread Variable mass system : water sprayed into a moving container.Here's my starting point. In the rest frame of the container, a small mass of water ##\Delta m## is ejected in time ##\Delta t## at...

Welcome to the forum. Please do take the time to read the rules here - the forum is for the discussion of mainstream science only. If...

PeroK replied to the thread Variable mass system : water sprayed into a moving container.That's what I get with the assumption that the jet is never a significant distance from the container.

Definitely, physics forum is a go to ! Especially when chatGPT doesn't correct my approach instead just gives solution. I expect Physics...

What about us at Physics Forums? The ChatGPT solution matches mine. I recommend that you read this article which includes a...

Haha.
Unfortunately the Examiner hasn't provided any solution, neither any standard textbooks have a similar problem as far as i know. so my... -

To @Su6had1p : I have a solution under certain assumptions. Please post the answer that you are told is correct to compare. Note that...

PeroK replied to the thread Variable mass system : water sprayed into a moving container.The simplest interpretation is that the cannon follows the container and effectively all the water ejected is in the container at time...
