https://www.ipho.org/problems-solutions This is the holy grail. The official IPhO archive contains every problem and solution from 1967 to the present. Problems are presented in English and the official working language. Why use it? Authenticity. If you can solve the last 10 IPhO mechanics problems (e.g., “Spinning Cylinder on a Table” or “Collision of Galaxies”), you are ready for any national team selection camp.

This problem tests your understanding of torque and friction directions. Let be the forward linear acceleration and be the angular acceleration. For rolling without slipping, Step 2: Force and Torque equations. Linear translation: (assuming static friction acts forward). Rotation about center: Step 3: Solve for acceleration. From the torque equation, . Substitute this into the linear equation:
