Solution

The document outlines calculations related to work, force intensity, mechanical energy, angular velocity, and motor torque in a physics problem involving a pulley system and a solid body. It includes formulas and numerical values for various parameters, such as work done by weight and tension, as well as the final distance after the system's components interact. The calculations assume negligible friction and provide a structured approach to solving the problem step by step.
