Question

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_i = 40.0 m/s and at an angle of θ_i = 42.0° above the horizontal. The base of the hose (at ground level) is a horizontal distance d = 45.0 m 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 v_i at an acute angle θ_i, above the horizontal and curves downwards Just before it strikes the building at height h above the ground. The building is a horizontal distance d from the fireman.
