**Projectile Motion Problem**
A ball is tossed from an upper-story window of a building. The ball is given an initial velocity of **8.90 m/s** at an angle of **21.0° below the horizontal**. It strikes the ground **4.00 s** later.
1. **How far horizontally from the base of the building does the ball strike the ground?**
- **Answer:** 33.2 m ✔️
2. **Find the height from which the ball was thrown.**
- **Answer:** 81.58 m ❌
- **Note:** Work only with the vertical components of these quantities. This part of the problem is then a 1-dimensional free-fall example.
3. **How long does it take the ball to reach a point 10.0 m below the level of launching?**
- **Answer:** 1.14 s ✔️
For further understanding, it's crucial to break down the components of the ball's motion into horizontal and vertical segments, utilizing kinematic equations and vector decomposition.
