Where can I find online resources to help with classical mechanics?

Hi!

My classical mechanics course is proving to be quite a challenge. The textbook has not arrived yet, and my professor has already assigned a problem set. For example, one question is

A bead of mass m is constrained to move along a smooth conical spiral. The radius of the spiral ρ = a z and the angle along the spiral φ = - b z where ρ, φ and z are the standard cylindrical coordinates. Find the equation of motion of the bead.

I have no idea where to start because we don't do any examples of worked problems in class, only theory and proofs. Does someone know any good online resources that I can check out?

Thanks

Essentially you can find z as a function of time. The rest are constraints. Write down the Lagrangian in terms of rho, phi and z, then substitute where applicable.

for reaching out for help with your classical mechanics course. It can be challenging to learn new concepts without the proper resources and guidance. One suggestion I have is to try searching for online lectures or tutorials on classical mechanics. There are many universities and educational websites that offer free resources for students to learn from. You could also try reaching out to your professor or classmates for assistance or clarification on the problem set. Additionally, practicing similar problems and working through them step by step can also help improve your understanding of the material. Best of luck with your studies!
