Physics Canon Ball Help?
The question is:
A canon ball is fired at a target x distance away. The target is y distance above the ground.
What angles should the canon be fired to hit the target?
I'm not sure how I would even start the question.
lets say..
x=200
y=50
And Vi=75m/s
Does the trajectory follow a parabolic shape still even though the target already has y distance above the ground?

[gx²/(2Vi²)]*tan²Θ - x*tanΘ + [gx²/(2Vi²)] + y = 0
Solve this quadratic for tan Θ; the 2 answers will give the 2 angles which will result in a 'hit'.
