• 1.A baseball is batted at an angle into the air. Once airborne, and ignoring air drag, what is the ball's acceleration vertically? Horizontally?
• 2. At what part of its trajectory does the baseball have a minimum speed?
• 3. Consider a batted baseball that follows a parabolic path on a day when the Sun is directly overhead. How does the speed of the ball's shadow across the field compare with the ball's horizontal component of velocity?
