The blue ball is thrown into the air and follows a parabolic path.  How does its velocity change with time?

Hints

  1. Using techniques developed earlier, measure the x and y components of the ball's velocity near the beginning of the motion.
  2. Measure the x and y components of the ball's velocity near the end of the motion.
  3. Did the x component change? The y component?
  4. What causes the change in velocity?
