A fireman d = 46.0 m away from a burning building directs a stream of water from a ground-level fire hose at an angle of 0, = 38.00 above the horizontal as shown in the figure. If the speed of the stream as it leaves the hose is v; = 40.0 m/s, at what height will the stream of water strike the building? X Your response differs from the correct answer by more than 10%.
