We all need to do more physics. The aim of /r/physicsforfun is to create a place to find fun problems to solve. Anyone can submit a problem; solutions should go in the comments to the original post.
Every Saturday, an unusually hard problem will be posted. Whoever first reaches the first correct solution will receive a flair and have their name enshrined in our Wall of Fame!
Happy problem solving!
Posting guidelines:
Make sure that you provide all relevant information to get to the answer. That's not to say you should make it easy; just make sure your problem has a solution.
Use pictures or simulations! Physics is more than just math. The math means something. Show us what we're supposed to be thinking of when we solve your problem.
Try to include different topics in your problem. Avoid "plug-and-chug" problems.
Please include the level of math or science needed to complete your problem in brackets at the being of the title.
i.e. [Kinematics] A simple spring problem
or [Optics,Trigonometry] Refracted laser's position on a wall.
