SUMMARY
The discussion centers on calculating the horizontal distance from a cliff to the Black Pearl ship, given that a cannonball is fired at 50 m/s at an angle of 30° from a height of 100 m. The vertical displacement (Delta y) is -100 m, indicating the cannonball descends to sea level. The horizontal (Vx) and vertical (Vy) components of the initial velocity are calculated using the equations Vx = v cos(theta) and Vy = V sin(theta). These calculations are essential for determining the exact distance to the ship.
