Jeff and I were playing on the Merry-Go-Round at the local park. It was very large. We stood on opposite sides and spun the Merry-Go-Round counter-clockwise. I threw a ball to Jeff. From my perspective, did the ball go to Jeff, or did it go to the right of him or the left of him?

Answer
Since the Merry-Go-Round has moved while the ball is travelling to Jeff, the ball will go to the right of him.
