Finding velocity for projectile given distances and launch angle

[QUOTE="kuruman, post: 6847012, member: 192687"] I can only speak for myself when I say that I could be more helpful if understood your numbers and how you got them. I am baffled by equations like 35 = sin55 (250/cos55) - (306250/v^2cos3025) Do you really mean cos3025? Where did you get an angle equal to 3025 in , I assume, radians? I strongly recommend that you work out the solution algebraically without using numbers to get an expression for ##v^2## in terms of the projection angle ##\theta##, the horizontal distance ##x##, the wall height ##h## and, of course, ##g##. Then substitute the numbers. This would help us figure out (a) whether you got the wrong expression and where you went wrong or (b) whether you made a mistake in substituting the numerical values.
