Explain why the horizontal component of velocity remains constant for a horizontally launched projectile.

• Because there is no horizontal acceleration acting on the projectile.

• Because the vertical motion affects the horizontal motion.

• Because air resistance increases the horizontal velocity.

• Because gravity acts in the horizontal direction.

• 2.02 seconds

• 3.19 seconds

• 4.52 seconds

• 5.10 seconds
