O řr and Fa and Ě, Submit Request Answer Usually the best advice is to choose a coordinate system so that the acceleration of the system is directly along one of the coordinate axes. If the system isn't accelerating, then you are better off choosing the coordinate system with the most vectors along the coordinate axes. But now you are gaing to ignore that advice.…
