![### Fireman Aiming Water Stream at a Burning Building
A fireman \( d = 57.0 \) m away from a burning building directs a stream of water from a ground-level fire hose at an angle of \( \theta_i = 23.0^\circ \) above the horizontal, as shown in the figure. If the speed of the stream as it leaves the hose is \( v_i = 40.0 \) m/s, at what height will the stream of water strike the building?
\[ \boxed{\text{____________}} \text{ m} \]
### Diagram Explanation
The given figure illustrates the scenario:
- A fireman is standing on the ground, aiming a hose at an angle \( \theta_i = 23.0^\circ \) relative to the horizontal.
- The water stream travels in a parabolic arc, with an initial speed \( v_i = 40.0 \) m/s.
- The distance from the fireman to the building (horizontal distance) is \( d = 57.0 \) m.
- The height \( h \) is where the stream will strike the building.
This setup involves projectile motion, which can be analyzed using physics equations to determine the height \( h \).
### Graphical Elements
- A fireman is depicted directing a hose towards a burning building.
- The water trajectory is shown as a blue parabolic curve.
- Relevant parameters are labeled: horizontal distance \( d \), angle of projection \( \theta_i \), initial speed \( v_i \), and height \( h \) where the stream hits the building.
This problem requires understanding projectile motion principles to find the required height at which the water stream strikes the building.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F6b165613-2027-4238-9c7e-a40fd74e53eb%2Ff548deab-506b-44d9-af49-9ba2c0a601ca%2F02j5ifo.png&w=3840&q=75)
