The first semester of an undergraduate physics course invariably spends a lot of time on two big ideas: The momentum principle and the work energy principle. Both deal with forces acting on an object, ...
Since the problem asks for a relationship between the change of speeds of A and B, and the distance traveled by B, the work/energy equation is a natural method of choice. Recall that with the ...
