At which angle the maximum height attained by aprojectile is maximum ?

Explanation

To determine the angle at which the maximum height attained by a projectile is maximum, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Formula for Maximum Height**:
The formula for the maximum height \( H \) attained by a projectile launched with an initial velocity \( u \) at an angle \( \theta \) is given by:
\[
H = \frac{u^2 \sin^2 \theta}{2g}
