a fireman D=50 m away from a burning building directs a stream of water from a ground-level fire hose at an angle of 30 degrees 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?

  • physics help - ,

    horizontal speed= 40cos30
    time to hit building= 50/40cos30 figure that out.

    Vertical height.
    h= 40sin30*t-1/2 g t^2 put time t in, figure h.
