Water from a fire hose is directed toward a building as shown in the figure below. The water leaves the hose at a speed of v; = 40.0 m/s and at an angle of 8, = 43.0° above the horizontal. The base of the hose (at ground level) is a horizontal distance d = 49.0 m away from the building. Find the height h (in m) where the water strikes the building. m

Question
**Projectile Motion of Water from a Fire Hose**

**Description:**

Water from a fire hose is directed toward a building as shown in the accompanying diagram. The water exits the hose with an initial velocity (\(v_i\)) of 40.0 m/s at an angle (\(\theta_i\)) of 43.0° above the horizontal axis. The base of the hose, located at ground level, is positioned at a horizontal distance (\(d\)) of 49.0 m from the building. The objective is to calculate the height (\(h\) in meters) where the water impacts the building.

**Diagram Explanation:**

- The diagram illustrates a firefighter aiming a hose towards a building.
- The trajectory of the water follows a parabolic path starting from the hose to the point of impact on the building.
- The key parameters include:
  - Initial velocity (\(v_i = 40.0 \, \text{m/s}\))
  - Angle of projection (\(\theta_i = 43.0^\circ\))
  - Horizontal distance to the building (\(d = 49.0 \, \text{m}\))
  - Height of impact (\(h\)), which needs to be calculated.

The cross-section of the scene includes the hose at the origin point and the building at the horizontal distance where the water strikes at height \( h \).

**Interactive Component:**

An input box is provided for users to calculate and input the height \( h \) (in meters) using the given parameters of projectile motion.
