Solve the below problem:
Q: An oscillating water sprinkler is operated at point A on an incline that forms an angle a with the horizontal. The sprinkler discharges water with an initial velocity v0 at an angle f with the vertical which varies from - f0 to + f0. Knowing that v0 = 24 ft/s, f0 = 40°, a = 10°, determine the horizontal distance between the sprinkler and points B and C which define the watered area.
