A fireman d=37.0m away from a burning building directs a stream of water from a ground-level fire hose at an angle
A fireman d=37.0m away from a burning building directs a stream of water from a ground-level fire hose at an angle of θi=33.0° above the horizontal as shown in the figure. If the speed of the stream as it leaves the hose is vi=40.0m/s, at what height will the stream of water strike the building?

Problem 6.077 Incorrect. A fireman is soaking a home that is dangerously close to a burning building. To prevent water damage to the inside of the neighboring home, he throttles down his flow rate so that it will not break windows. Assuming the typical window should be able to withstand a force up to 30 lbf, what is the largest volumetric flow rate he should allow (gal/min.), given an 10 inch diameter (D1) firehose discharging through a nozzle with 3-inch...
