If a baseball pitch leaves the pitcher’s hand horizontally at a velocity of $ 150 $ $ \text{km/h} $, by what $ \% $ will the pull of gravity change the magnitude of the velocity when the ball reaches the batter, $ 18 $ $ \text{m} $ away? For this estimate, ignore air resistance and spin on the ball.

If a baseball pitch leaves the pitcher&#8217;s hand horizontally at a velocity of $ 150 $ $ \text{km/h} $, by what $ \% $ will the pull of gravity change the magnitude of the velocity when the ball reaches the batter, $ 18 $ $ \text{m} $ away? For this estimate, ignore air resistance and spin on the ball.
