Rigid bodies are outside the purview of Newtonian mechanics, as Newton himself seems to have admitted in The Principia. However, the application of D'Alembert's Principle yields a solution to this simple problem. The problem becomes particularly simple when worked out for a thin cylinder or ring rolling down an inclined plane. Should high school students be introduced to D'Alembert's Principle?

What is the goal?
