1. The term "net moment" refers to the total moment (torque) resulting from all forces acting on a body. 2. By convention, a positive moment usually means a counterclockwise rotati

1. Let's clarify the terms: "moment of vertical" and "moment of horizontal" likely refer to moments about vertical and horizontal axes, commonly used in physics and engineering. 2.

1. **Problem Statement:** Given the motion equation:
