1D three-body problem (with spherical shell)

AI Thread Summary
The discussion revolves around the 1D three-body problem involving two point masses and a spherical shell, with specific initial conditions and equations of motion. Participants explore the possibility of solving for the positions of the masses as functions of time, questioning whether H and h are arbitrary functions of time. It is suggested that the complexity of the problem arises from the dependence of H and h on time. The thread concludes with the intention to move the discussion to a more appropriate section in Classical Physics for further exploration. The conversation highlights the challenges in solving dynamic systems in gravitational contexts.

Let's suppose that we have two point particles with masses m1,m2 and the spherical shell with mass M, placed in a line, at distances h1,h2 and H from 0 in that line (0 is the center of some inertial frame of reference). The initial conditions and the equations of motion are the following:

h_1(0)=H(0)=h_0

h_2(0)=0

h_1'(0)=h_2'(0)=H'(0)=0 (time derivative)

(the mass m1 is in the center of the spherical shell)\frac{dh_1^2}{dt^2}=-G\frac{m_2}{(h_1-h_2)^2}

\frac{dh_2^2}{dt^2}=G\frac{m_1}{(h_1-h_2)^2}+G\frac{M}{(H-h_2)^2}

\frac{dH^2}{dt^2}=-G\frac{m_2}{(H-h_2)^2}

Is there any way to solve this problem (to find the positions of the masses as functions ot the time)?

integrate twice with respect to t?

Or are H and h actually arbitrary functions of t?

Yes they are functions of t, i think, so it's more complicated.

Edit: I'm going to create the same thread in Classical Physics section so the moderators can close this one. Thnx!

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
I am attempting to use a Raman TruScan with a 785 nm laser to read a material for identification purposes. The material causes too much fluorescence and doesn’t not produce a good signal. However another lab is able to produce a good signal consistently using the same Raman model and sample material. What would be the reason for the different results between instruments?
