The discussion revolves around the suitability of "3000 Solved Problems in Physics" for physics majors, particularly regarding its inclusion of calculus-based problems. Users note that the book features a variety of problems, including challenging ones comparable to those in standard introductory physics texts like Resnick and Halliday. While the book contains many decent problems, the exact proportion of these within the total 3000 is questioned. Additionally, the lack of solved solutions in "Introduction to Mechanics" by Kleppner makes it difficult for users to verify their answers, highlighting the utility of the 3000 problems book. Overall, the resource is deemed beneficial for students seeking practice with calculus-based physics problems.
