Now, let’s address the elephant in the room. A search for will lead you down two paths: legal and illegal.
Use the repetition to your advantage. After 10 similar incline-plane problems, you will never forget how to resolve gravity components. Repetition builds automaticity.
The problems are not “conceptual” multiple-choice fluff. They are and sometimes repetitive.
Most of the problems have very little of the work shown in the solutions, making it hard to tell how it was actually done. Optics: PhysicsGRE.com
