2. The projected water will hit the wall in _____ s.
3. The maximum height that the water can reach is at _____
m from the ground.
4. The minimum velocity required for the water to reach the
bottom of the wall is _____ m/s.
5. Using the minimum velocity, at what height,
h1 in m, should the fireman hold the hose so that
the water will hit the wall at 5 m.
For the figure shown, the firefighter projects water from the hose at an angle of 50 degrees at a height of 1 m from the ground at a horizontal distance of 10 m away from the wall. The speed of the water that the hose nozzle is 15 m/s. (25 Points)
