A fire hose ejects a stream of water at an angle of 31.7° above the horizontal. The water leaves the nozzle with a speed of 26.5 m/s.?

Assuming that the water behaves like a projectile, how far from a building should the fire hose be located to hit the highest possible fire?

    ...

    find Vyi and Vx

    I use vector capable calculator

    026.5@31.7° = Vyi. Vx = 22.55 , 13.92 i

    find time to top of arc (highest point)

    t = Vyi / g = 22.55 / 9.81 = 2.30 s

    find x distance at that time

    x = Vx t = 13.92 * 2.30 = 32.0 m away

    When you get a good response,

    please consider giving a best answer.

    This is the only reward we get.

    R = (26.5²/9.8)sin(2•31.7) = _________ m

    you have a calculator

    range of object projected at an angle θ

    R = (V²/g)sin(2θ)

      V is initial velocity in m/s

      g is the acceleration of gravity 9.8 m/s²

      Is there anyway you can give me the final answers, I can not seem to find the right ones.
