You're quite welcome! Glad to help.

Replace L with 2L and compare the result to your original equation. Then find a way to express the mathematical relationship between those values in words. Don’t overthink it.

But should that matter? The question asks for instantaneous acceleration.

Looks to me like you're on the right track. Someone else please correct me if I'm wrong, but this looks like a simple vector addition problem.

If this is all the information you are given in the problem, then you cannot assume the length of the rope. Furthermore, the question appears to be asking you for the total acceleration of the bag in this reference frame. Think: if the boy stands still (holding the rope), what is the total...

Thank you so much! I found a version of this book to start looking through...lots to digest! :)

Appreciated, and I'm aware. QM will be my main focus, but I already have a solid foundation upon which to grow thanks to the excellent instruction I received as an undergrad. Also appreciated, and I likewise will be spending a good chunk of time learning programming. I'm not looking to become...

General interest and practicality. I want to get into quantum information/computing in the future, but I need to broaden my skill set. As such, I'm striving to learn as much about conventional computers (hardware and software) as possible, so I'm starting from basics.

Fair points: my wording was wrong. What matters is that the interaction force be conservative, whether or not this can be thought of as the manifestation of a field.

DrStupid: How do you mean? Do you have an example?

Sure thing: I just graduated with a B.S. in Physics with a minor in Mathematics. I'm comfortable/familiar with calculus and other selected mathematical methods, as well as undergraduate level physics (including a 400 level year long course on E&M). I do know Ohm's Law and the power relation...

If you're going to think of PE as a property of the particle in question (which, strictly speaking, it isn't), then you're not neglecting the PE contribution of the source at all. Why? Because the PE you're referring to only makes sense in the context of the interaction force of the "source" and...

As the title suggests, I'm hoping some of you have some favorite resources for a self-studying novice. I'm sure there are a LOT of places online (and in print) to learn, but if anyone can help point me in the right direction I'd be very appreciative. Cheers!

Hey folks, thought I'd ask the experts for some help here. I know that there are LOTS of online resources to learn Linux Terminal, Microsoft PowerShell, and Python, but I was hoping some of you had some favorites that might make the learning process more efficient (in your opinion, of course)...

It got harder every time I tried to quit. I started smoking when I was 17 years old. In December of 2018, I stopped smoking entirely but still dosed myself with nicotine with a vaping rig. Finally, I laid the vape down in May of this year (a week after graduation) and went through withdrawals...
