This is a projectile motion problem where a stone is thrown from the top of a building. Here is the breakdown of the given information:

- Height of the building, \( H = 164 \, \text{m} \)
- Initial velocity, \( v_0 = 43.3 \, \text{m/s} \)
- Launch angle, \( \theta = 30^\circ \)

You are tasked with finding the horizontal distance \( x \), which is how far the stone travels horizontally before hitting the ground.

### Step-by-Step Solution:

1. **Resolve the velocity components:**
   The initial velocity can be split into horizontal and vertical components.
   \[
   v_{0x} = v_0 \cos(\theta) = 43.3 \cos(30^\circ)
   \]
   \[
   v_{0y} = v_0 \sin(\theta) = 43.3 \sin(30^\circ)
   \]
   
2. **Time of flight:**
   Use the vertical motion to find the total time \( t \) it takes for the stone to hit the ground. The vertical displacement \( y \) is given by:
   \[
   y = v_{0y} t + \frac{1}{2} a t^2
   \]
   Here, \( y = -164 \, \text{m} \) (since it falls 164 m), \( a = -9.8 \, \text{m/s}^2 \) (acceleration due to gravity), and \( v_{0y} \) is the vertical component of the initial velocity.

3. **Horizontal distance (Range):**
   Once we know the time of flight \( t \), we can find the horizontal distance \( x \) using:
   \[
   x = v_{0x} t
   \]

Let me calculate the values for you.It seems that there was an issue with the calculation of the discriminant, which could be negative, causing a math error. This typically happens if there was an incorrect interpretation in the quadratic formula or initial setup.

Let me recheck the setup and correct the formula for vertical displacement. I will recompute.It seems like I can't do more advanced data analysis right now. Please try again later.

If you'd like, I can explain the steps in more detail or guide you through solving this manually. Let me know if you need help with any specific part of the problem.
