From the top of a cliff overlooking a lake, a person throws two stones, as shown in the drawing. The cliff is 17.9 m high. The two stones described have identical initial speeds of v0 = 13.7 m/s and are thrown at an angle θ = 36.6 °, one below the horizontal and one above the horizontal. What is the distance between the points where the stones strike the water? Neglect air resistance.
