Finding Work Done by Friction on a Sliding Block Against a Wedge

AI Thread Summary
The discussion focuses on calculating the work done by friction on a block sliding down a fixed wedge, which is shaped like a quarter circle. Participants emphasize the importance of applying the conservation of energy principle, noting that the normal force acting on the block is not constant and depends on its velocity. Several attempts to derive equations for the work done by friction and gravity are shared, with suggestions to set up differential equations to solve for the block's motion. The conversation also includes attempts to integrate these equations, with some participants expressing difficulty in evaluating certain integrals. Ultimately, the discussion highlights the complexity of the problem and the need for a systematic approach to find a solution.

You become a real scientist if you understand what you do. Maths and Physics are not mere collections of recipes. You have to start from the bases and build up your knowledge step by step. Every step must follow logically from your previous knowledge, and then you would feel a new theorem or proof easy as if you could have discovered them by yourself.
