A body is projected with a velocity of 30m/s to have to horizontal range of 45m. Find the angle of projection .

Explanation

To solve the problem of finding the angle of projection for a body projected with a velocity of 30 m/s to achieve a horizontal range of 45 m, we can follow these steps:

### Step 1: Understand the Range Formula
The horizontal range \( R \) of a projectile is given by the formula:
\[ R = \frac{u^2 \sin(2\theta)}{g} \]
where:
