Two Balls: One Dropped, one Shot Across

Here's the problem here: A stand holds two white balls. At the same instant the ball on the left is dropped straight down, the ball on the right is shot straight out towards the right.

The question is: Which ball will hit the ground first?

This video clip shows the two balls being launched.

This video is purposely stopped just after the balls are launched (we don't want to give away the answer!)

What do you think? Which ball will hit the ground first?

The left ball will hit first
The right ball will hit first
They will hit the ground at the same time.
