I'm having a hard time with the Irodov problems in General physics, especially with some of the last multistep problems as well as the waves/optics section, mainly because there are more advanced applications of extended object momentum, non-inertial frame, gyroscopic motion that I haven't learnt yet. Is there a rigorous undergrad level book that has many worked examples and can supplement well the Irodov Problems in General Physics? I have the Resnick Halliday, but its treatment seems way too simplistic for me to tackle olympiad level problems like those on Irodov. Here are the topics I need to strengthen: 1. Extended object mechanics (as well as kinematic relationships between interacting objects, which is widely used on pulley problems in Irodov) 2. non-inertial frames (was well as Work-Energy theorem in non-inertial frame) 3. Optics (especially the E&M aspect of optics) 4. gyroscopic motion 5. angular momentum Some problems I have a hard time, include: - rolling object hits a corner, - 2 mass connected by a spring are accelerated by a force - 2 masses connected by a spring vertically and both leaving the ground after releasing the spring?? - hideous pulley problems Thanks!
