Ahmed Čolić: Zbirka zadataka iz fizike za 2. razred gimnazije (English: Ahmed Čolić: Collection of Physics Problems for the 2nd Year of Gymnasium) is a well-established and widely used problem book in Bosnia and Herzegovina, as well as in other parts of the former Yugoslavia. It is specifically tailored to the second-year gymnasium curriculum (equivalent to Grade 10 or 11 in other systems), where students typically encounter the core branches of classical physics: thermodynamics, electromagnetism, and optics.
The book is designed to complement the standard physics textbook, providing a structured progression from basic recall problems to complex, multi-step challenges that prepare students for both school exams and competitive entrance exams (e.g., for medical, technical, or science faculties). ahmed colic zbirka zadataka iz fizike za 2 razred gimnazije

Weekly homework: At least 10 problems from the srednji (medium) group and 2 from teži (harder). Underline: given quantities (known)
Underline: given quantities (known), unknown (traži se), and implicit conditions (“from rest” means ( v_0 = 0 ), “smooth surface” means no friction).
Make sure you get the correct book. The title must explicitly say "za 2 razred gimnazije" (for 2nd grade gymnasium). There is also a version for technical schools (tehničke škole) which is easier, and a version for natural sciences (prirodno-matematički smjer) which is harder. The gymnasium version is the golden mean.
Example from Kinematika:
( v = v_0 + a t )
( s = v_0 t + \frac12 a t^2 )
