2) A firefighter who is a distance d from a burning building directs a stream of water from a firehose at an angle 0; above the horizontal, starting from essentially ground level. If the initial speed of the stream is vi, at what height h does the water strike the building? Note that the water is not actually hitting the building at the top of the arc so vy#0. (Hint: You can first get the time of travel to go a distance d in the x-direction in terms of the initial quantities.) 18, d h
