C)of no initial vertical component of velocity.
D)all of the above
E)none of the above

Quizplus · Accepted Answer

With no air resistance, the only force acting on the projectile is gravity, which acts vertically downwards. Since there are no horizontal forces acting on the projectile, its horizontal component of velocity remains constant. The initial vertical component of velocity may or may not be present, but it does not affect the horizontal component of velocity.

With No Air Resistance a Projectile Fired Horizontally Maintains Its
