An oscillating water sprinkler is operated at point A on an incline that forms an angle ? with the horizontal. The sprinkler discharges water with an initial velocity v0 at an angle ? with the vertical which varies from ?? ?0 to + ?0. Knowing that v0 = 24 ft/s, ?0 = 40?, ? = 10?, determine the horizontal distance between the sprinkler and points B and C which define the watered area.
