away from the building. Find the height h (in m) where the water strikes the building.
A fireman on the ground sprays water from a fire hose onto a building. The water leaves the hose with velocity vector vi at an acute angle θi above the horizontal and curves downwards just before it strikes the building at a height h above the ground. The building is a horizontal distance d from the fireman.

- A city holding tank for water sits 21.0 above the city. If a house near the holding tank was on fire, to what height would firefighters have to drain the tank so water sprayed from the bottom of the tank hits the top of the house at its center, 10.0 m above the ground and 12.0 m away? QUESTION 2 Consider the water tank from the previous question. What is the speed (in m/s) of the water as it leaves the bottom of the tank? QUESTION 3 Assume the tank from the previous questions is sealed airtight with an air gap between the water's surface and the top of the tank. The air pressure in the air gap is 25.0 kPa, while atmospheric pressure outside the tank is 101.4 kPa. Assuming the velocity of the water level in the tank is effectively zero, to what height will firefighters now need to drain the tank so water hits the burning house?
