SUMMARY
The horizontal distance a cannonball travels when fired from an angle θ on a sloped surface is calculated using the formula dx = 2v²cos(o)sin(O + o)/gcos(O), where v is the initial velocity, o is the angle of projection, O is the slope angle, and g is the acceleration due to gravity. The discussion emphasizes the importance of understanding the intersection of the projectile's flight path with the slope's equation. Key trigonometric identities, such as sin(O + o) = sin(O)cos(o) + sin(o)cos(O), are also highlighted as essential for deriving the distance formula.
