The statement of Problem 4 ("just you wait, rocket!") included requirements that cannot generally be satisfied at the same time. Therefore, it is sufficient to solve the problem for small angles ($\theta \ll 1$). We have already updated the assignment on the website. We also want to let you know that we are extending the submission deadline for Problems 4 and S (X-ray methods) until March 8, 2026, at 11:59 PM. We apologize for the inconvenience and wish you the best of luck with the solutions!

This year's Fyziklání is successfully behind us. You can already find the assignment and solutions to the problems or how the teams performed on the our website. At the same time, you can look forward to photos from the competition in the near future.
