What do you mean by maximum height attained by a projectile ?

Explanation

### Step-by-Step Solution

1. **Understanding Maximum Height**:
- The maximum height attained by a projectile refers to the highest vertical position reached by the projectile during its flight. It is measured as the vertical distance from the ground (or the launch level) to the highest point of the projectile's trajectory.

2. **Projectile Motion Overview**:
- When a projectile is launched with an initial velocity \( v \) at an angle \( \theta \) with respect to the horizontal, it follows a parabolic path due to the influence of gravity.
