This problem is practically identical to the one I just showed you how to do with the two cliffs.
horizontal:
u = 44.1 cos 31.3 forever
t = 43.7/u
vertical
h = 0 + Vi t - 4.9 t^2
where Vi = 44.1 sin 31.3
A fireman, 43.7 m away from a burning building, directs a stream jet of water from a ground level fire hose at an angle of 31.3 degree above the horizontal.
If the speed of the stream as it leaves the hose is 44.1 m/s, at what height will the stream of water strike the building? The acceleration due to gravity is 9.8 m/s^.
Answer in units of m.
