What are the x- and y-coordinates of the shell where it explodes, relative to its firing point? 32. A fireman 50.0 m away from a burning building directs a stream of water from a ground-level fire hose at an angle of 30.0° above the horizontal. If the speed of the stream - as it leaves the hose is 40.0 m/s, at what height will the stream of water strike the building? A 9.00-m-tall basketball player is standing on the floor Ochehoots
