MY NOTES ASK YOUR TEACHER 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 = 44.0 m away from the building. Find the height h (in m) where the water strikes the building. 4.
