A firefighter is standing on top of a building 19 m high, holding a firehose 1 m above the top of the building. She finds that if she holds the hose horizontally the waterflows from it at 12 m/s. As this happens, the water hits an adjacent burning building at a height of 15 m above the ground. (The gravity constant is 9.8 m/s².) Set up (but do not evaluate) an integral that would compute the length of the water stream from the hose to the building on fire.
