SUMMARY
The calculation of energy dissipated by friction in physics problems is fundamentally based on the law of conservation of energy. To determine the energy E dissipated by friction when a block comes to a stop, one must utilize the equation sqrt(v^2 + 2gh), where m represents mass, v is the initial velocity, g is the acceleration due to gravity, and h is the height. The discussion highlights the necessity of complete information to accurately solve for E, emphasizing that missing variables can hinder the solution process.
