Question: A fireman d = 60.0 m away from a burning building directs a stream of water from a ground-level fire hose at an angle of θi = 36.0° above the horizontal as shown in the figure. If the speed of the stream as it leaves the hose is vi = 40.0 m/s,
Part A: At what height will the stream of water strike the building?
