4. 4A person throws a ball straight up in the air. The ball rises to a maximum height and then falls back down so that the person catches it. Consider the ball while it is in the air. Which of the following statements are true?
   

   1. AJust after the ball leaves the person's hand the direction of the acceleration is up.
   2. BThe acceleration is zero when the ball reaches its maximum height.
   3. CThe acceleration is about 9.8 m/s2 (down) when the ball is falling.
