The acceleration due to gravity is always down word i.e., along the -ve y direction can be choose this direction as the positive direction for the acceleration due to gravity

Explanation

To solve the question regarding the choice of direction for the acceleration due to gravity, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Direction of Gravity**:
- The acceleration due to gravity (g) always acts downward towards the center of the Earth. In a Cartesian coordinate system, this direction is typically represented as the negative y-direction.

2. **Choosing the Positive Direction**:
...
