Plava Zbirka: A Comprehensive Collection of Physics Problems by Nada Brkovic

Plava Zbirka (Blue Collection) is a popular and modern book of physics problems for high school students, written by Nada Brkovic, a long-time physics teacher at the XV. Gymnasium in Zagreb, Croatia. The book covers the entire physics curriculum in 12 chapters, such as mechanics, heat, electricity, oscillations, waves, optics, relativity, quantum physics and nuclear physics. It contains 4000 problems, with many illustrations and solutions[^1^].

The book is intended to help students prepare for exams, competitions and entrance tests for universities. It also aims to stimulate their interest and curiosity in physics, as well as to develop their problem-solving skills and logical thinking. The book is widely used and praised by students and teachers alike, as well as by physicists and other professionals who appreciate its rigor and clarity[^2^].

The second problem in the 122nd page of the book is about the conservation of momentum in a collision between two carts on a frictionless track. The problem asks to find the final velocities of the carts after the collision, given their initial velocities and masses[^3^]. The solution involves applying the conservation of momentum principle and solving a system of two equations with two unknowns.

Plava Zbirka is a valuable resource for anyone who wants to learn or practice physics at a high level. It is available in three volumes in a cardboard box from the publisher "LUK" Zagreb[^1^]. It can also be found online in PDF format[^3^], but without detailed explanations of the solutions.

Plava Zbirka has received many positive reviews from its users, who appreciate its quality and usefulness. Some of the comments on Reddit[^2^] are:

"NeÅ nauÄit ÄitajuÄi zadatke frende, trebaÅ ih sam" (You won't learn by reading the problems, friend, you have to do them yourself)

"Ma sve 5 s tim al nekad bude baÅ napredni zadatak za koji bi pomoglo za skuÅit" (It's all good with that but sometimes there is a really advanced problem that would help to understand)

"Za teÅe zadatke doslovno ima postupak" (For harder problems there is literally a procedure)

"Nama je profesor govorio da samo predlaze da rijesavamo domacu zadacu (ta plava zbirka) ,i da nas on ne mislis tjerat sa jedinicama, da smo klipani veci i da sami moramo odluciti hocemo li se trgnut ili ne..." (Our teacher told us that he only suggests that we do our homework (that blue collection), and that he doesn't think of forcing us with grades, that we are big kids and that we have to decide for ourselves whether we will get up or not...)

Plava Zbirka is not only a book of physics problems, but also a cultural phenomenon in Croatia. It has inspired many memes, jokes and anecdotes among students and teachers. Some examples are:

"Plava zbirka je kao Biblija - svi je imaju, nitko je ne Äita" (Plava Zbirka is like the Bible - everyone has it, no one reads it)

"Kad ti profesor kaÅe da rijeÅiÅ zadatak iz plave zbirke" (When your teacher tells you to solve a problem from Plava Zbirka)

"Kako se zove plava zbirka na engleskom? Blueberry" (What is Plava Zbirka called in English? Blueberry)

Plava Zbirka is a testament to the passion and dedication of Nada Brkovic and her collaborators, who have created a masterpiece of physics education that has influenced generations of students and teachers. It is a book that deserves respect and admiration from anyone who loves physics.
