    Spring - Pulley - Mass system. Proving omega is a certain value

    Homework Statement Hello, everyone. I am a starting physics student. I know a little bit of calculus and mechanics. I have been solving a lot of problems successfully, but I come back to being stuck on this one. I will show you what I have done and I hope you can be kind enough to give me a...

    Spring Paradox (apparently). Energy problem with one vertical spring.

    Oh wait. If... there are no other forces, wouldn't it oscillate instead of just sitting there? When you release the mass, realistically it would go beyond the equilibrium point then back up, and keep oscillating. I assumed that 'eventually', it would stop moving. But that's only because in...

    Spring Paradox (apparently). Energy problem with one vertical spring.

    *slaps forehead* I should have seen that. O_O The paradox is clear now. What's not clear is how did this happen. There are no other forces acting on it. That 2 shouldn't be there. I'm beyond exhausted, going to have to sleep on it. Thank you very much! (It seems weird to say 'thank you very...

    Spring Paradox (apparently). Energy problem with one vertical spring.

    Apologies if this is too basic, but I've been studying for a while and I'm stuck. Homework Statement Spring paradox. What is wrong with the following argument? Consider a mass m held at rest at y = 0, the end of an unstretched spring hanging vertically. The mass is now attached to...
