Explanation:
• t2<span>). Furthermore, since there is no horizontal acceleration, the horizontal distance traveled by the projectile each second is a constant value - the projectile travels a horizontal distance of </span>20 meters<span> each second. This is consistent with the initial horizontal velocity of </span>20 m<span>/s.
