Confusion about Instructor's solution of HRK

[QUOTE="TSny, post: 6809021, member: 229090"] Perhaps the solution in the manual interprets the horizontal range R (350 ft) to be the horizontal distance that the ball would travel before it returns to its initial height of 4 ft above the ground (assuming the ball clears the fence). Then, ##v_0 = \sqrt{gR}## is OK. I'm not defending this interpretation, but it might be what was going on in the mind of whoever wrote the solution. Who knows. I'm with you in interpreting the horizontal range as the horizontal distance traveled until landing on the ground. It's fairly common for solution manuals to have occasional errors. [/QUOTE]
