### Physics Problem: Projectile Motion

From the window of a building, a ball is tossed from a height \( y_0 \) above the ground with an initial velocity of **8.10 m/s** and an angle of **21.0°** below the horizontal. It strikes the ground **6.00 s** later.

---

In this scenario, the ball undergoes projectile motion, influenced by gravity, affecting both its vertical and horizontal components of motion. Notice the given parameters:

- Initial velocity (\( v_0 \)) = **8.10 m/s**
- Angle of projection \( (\theta) \) = **21.0° below the horizontal**
- Time of flight (t) = **6.00 s**

To solve for various parameters such as the range, maximum height, or the final velocity upon impact, we would need to decompose the initial velocity into horizontal and vertical components and apply the kinematic equations. 

---

#### Key Concepts:

- **Vertical Motion**: Governed by the acceleration due to gravity (9.8 m/s²).
- **Horizontal Motion**: Constant velocity as there’s no horizontal acceleration (assuming negligible air resistance).

The details given, help in understanding the dynamics and the subsequent calculations which can include determining the height of the window (\( y_0 \)), the range (\( x \)), and the final velocity components just before the ball strikes the ground.
