Which statement describes the horizontal motion of a horizontally launched projectile? the projectile’s acceleration is zero, so its velocity is zero. The projectile’s acceleration is –9. 8 m/s2, so its velocity is changing. The projectile’s acceleration is zero, so its velocity is constant. The projectile’s acceleration is –9. 8 m/s2, so its velocity is constant.
