Drop Ball and Throw Ball

Two balls are allowed to fall simultaneously. One ball is projected horizontally, while the other is released from the same height to fall straight down. Within experimental uncertainty, their vertical motions are clearly common in that they are at the same elevation at each point in time.
Equipment:
- Two balls
