Evidence boundary
The complete item is Part A Q6 of The Physics Classroom's Vectors and Projectiles Review. The seventh statement is wording-dependent; this page preserves that caveat. Claims about negligible drag, constant downward gravity and possible zero horizontal velocity use the standard idealized near-Earth projectile model; no launch speed or trajectory was specified, so none is fabricated.
