A physics demo launches a ball horizontally, while dropping a second ball vertically at exactly the same time.
1)Which ball hits the ground first?
Launched (horizontally) ball
Dropped ball
Both hit at the same time.

The answer should be "both hit at the same time" right, because they have the same y-final, y-initial, initial velocity, and acceleration due to gravity?
