I used the wrong word there. I apologise. So, I would really like to know how to calculate how close a project like that would be from the moon. Assuming, of course, that the people inside the capsule would resist the acceleration. I'm quite new to aerospace and more so to ballistics. I...

Using the values from the book in a programme and calculating the time, deceleration and how close to the moon it would get.

Has anybody attempted simulating the trip to the moon described by Jules Verne? I've done a bit of research and found this two posts: https://www.physicsforums.com/threads/showing-deadly-acceleration.909104/#post-5726115...

I understand. My problem is that I'm trying to validate the results of a simulation that is constrained to the Euler angle equations where both the Z and e3 axes are parallel. My german is not that good, but from what I understand, your approach also aligns the Z axis with the constant angular...

Is calculating the Euler angles analitically possible? I am trying to obtain the angles to transform the body-fixed reference frame to the inertial reference frame. I can get them without problems with numerical methods. But I would to validate them analitically, if possible. I followed the...

It is all clear now. Thank you very much.

Thanks for answering. Yes, but we were told to change the input to one of our choosing. And I chose sin() to have a simple input. So, if I leave Θ=0 and without a forcing function, I could still do something like: x(0)=C_1e^{-0}+C_2e^{-3(0)}=C_1+C_2 and with an input=0, C1=-C2, right? How? I...

Thank you, it is good to know that I'm on the track. I made a mistake on the particular solution part, I chose it to be: x_p(t)=a_1sin(\omega t + \frac{\pi}{4})+a_2cos(\omega t + \frac{\pi}{4}) so: \frac{dx_p(t)}{dt}=\omega a_1cos(\omega t + \frac{\pi}{4})-\omega a_2sin(\omega t +...

Thank you all for answering. It was my mistake to mix radians and degrees. Please assume that Θ = π/4. The teacher gave us this equation: A*cos(\omega t)=\frac{md^2x(t)}{dt^2}+\frac{bdx(t)}{dt}+kx(t) With x(0) = X_0\neq 0 \frac{dx(0)}{dt} = V_0\neq 0 We need to set an input (which I set to...

Homework Statement Solve: A*sin(ωt + Θ) = L*i''(t) + R*i'(t) + (1/C)*i(t). Where: A=2, L = 1, R=4, 1/C = 3 and Θ=45°. Homework Equations The system has to be solved by i(t) = ih + ip. I gave the values to A, L, R, 1/C and Θ. I can also give values to ω, but I've come to a doubt when solving...

I just joined today, I am an undergraduate electronic engineer looking forward to go deeper in physics, mechanics and similar things and learn from experts. So hello!
