In a homework problem for this course, students are asked to consider the motion of a system made up of a plate (having a mass of m) which is pinned to a cart B (having a mass of M) at corner O. The ...

For this problem using the linear impulse-momentum equation, work with the system of A+B+C as a whole when looking for motion. If you then need to find internal forces to the system, consider ...

In an introductory physics course, there are three big ideas. There is the work-energy principle, the momentum principle and then the angular momentum principle. I'll skip the work-energy principle ...
