Josh's physics picks: September 13, 2015

Each week, I'll be choosing four or five of the most fun and interesting problems (in my opinion) I see in the community and posting them in a set. I'll be keeping an eye on the solutions, and at the end of the week will do a writeup on those I find exemplary. I'll also point out interesting things about the topics and where possible, show how to extend the thinking to more general situations.

Here is the first set

I hope you enjoy my selections and get something out of working on them. I'm looking forward to seeing everyone's work.

Josh

Hey Sam, the picture is from the cover of "Einstein Gravity in a Nutshell" by Anthon Zee. I don't know who the artist is, but that's where I saw it.
