Question

Which of the following is the BEST way to select a coordinate system?

A. make sure that the acceleration vector falls at a 45° angle from the x-axis


B. make sure that the coordinate system has the x-axis as horizontal and the y-axis as vertical


C. make sure that any acceleration vector falls along one of the major axes of the coordinate system


D, make sure that the coordinate system has the x-axis as vertical and the y-axis as horizontal

Answer 1

C. make sure that any acceleration vector falls along one of the major axes of the coordinate system

Step-by-step explanation:

C. make sure that any acceleration vector falls along one of the major axes of the coordinate system

Since this simplifies calculations, otherwise you would have to break the acceleration vector into x and y components and so on.

Can become a mess...
