SUMMARY
The discussion focuses on determining the appropriate equations for calculating the range of upward projectiles in physics. Two methods are highlighted: the range equation and a derivation method. The textbook states a displacement of 40m based on a launch speed of 20 m/s, while the user calculated a displacement of 123m. The conversation emphasizes that both methods are valid under certain conditions, and the choice of method depends on the specifics of the problem, including whether the projectile is launched from an inclined plane.
