    Rocket Launched Up When a Stone is Dropped Down

    Yes, your work is correct.

    Undergrad Rod elastically impacting a ball - impact location

    Do you think that that would lead to an interesting solution? How would it be different from two balls colliding? Like many problems, the first step here is to come up with a model that is neither so complicated that the solution is intractable nor so simple that that the solution is trivial...

    Undergrad Rod elastically impacting a ball - impact location

    Clearly we have to consider the limiting case as the duration tends to zero.

    Undergrad N-Queens: Total Queen Count Patterns

    It is not clear from your post what you have noticed, perhaps you should look at it again and consider whether you have actually observed anything non-trivial at all. Yes, the two solutions for n = 4 are symmetric. We say that there is only one fundamental solution for n = 4. The count of the...

    Rocket Launched Up When a Stone is Dropped Down

    Yes that is correct. Were you required to find h to answer the question? This sentence does not make sense. Perhaps there is a problem with translation?

    Why not look at the examples on this page?

    Obscure English Language Question...

    Peter actually says "look there's a dog tied to a other dog". This is of course not correct grammar, and is something that only [someone as inane as] Peter would say. In this episode ("Boopa-dee bappa-dee"), Peter and Lois are recalling a helicopter sightseeing trip that he and Lois took over...

    High School XOR operand distinction

    You can find out if an operand is true by looking at it. If this does not answer your question you need to provide more context.

    Comp Sci A question on solution 6.1-2 from CLRS

    Yes but you didn't fix this: ...although that is obviously what you mean if you have derived ## m=\log_2(n−k+1) ##. Anyway you are looking at this the wrong way round: ## m=\log_2(n−k+1) ## is not much help. Instead read the solution and consider how many elements there are in a heap of...

    Yes, it is fun. Online gaming interrupted by som real life sporting events at the moment though!

    Options for fixing power connector on Acer laptop

    This could be a concern, but the fact that it charges at all over USB C indicates that it will be plenty - it wouldn't be worth implementing PD otherwise.

    Options for fixing power connector on Acer laptop

    That would work but I think you would find something like this more versatile: https://a.co/d/04Y7H582 - you could charge your phone too at the same time. You'll also need cables e.g. https://a.co/d/0idWyBHy

    Options for fixing power connector on Acer laptop

    Is this an Aspire? I wouldn't go anywhere near it with any kind of soldering equipment, in fact I wouldn't even take the case apart unless I was prepared to hold it together with duct tape for ever after. Those things are built down to a price and are effectively unmaintainable. If you can use...

    Managing passwords across Apple Keychain and Chrome password manager

    They do but they don't talk to each other (Windows <-> Android) so a (paid for) 3rd party password manager is most convenient, and will also store credit card details for cross-platform use. I use 1Password.

    Announcement PF Style 2026

    Yes, but because Sci-Fi Writing and World Building was already a child of Science Fiction and Fantasy Media it has now ended up a grandchild of General Discussion. Are there any other grandchild forums, and if not then why not make Science Fiction and Fantasy Media Sci-Fi Writing and World...
