A ball is thrown horizontally off a building that is 30 m high with an initial velocity of 3 m/s.if an identical ball is thrown again horizontally from the same height with 6 m/s, what happens to the flight time?
A. Flight time is doubled.
B. Flight time is decreased by half.
C. Flight time is the same.
D. Flight time is exponentially increased.
I don't understand the material very well. If you could explain and tell me, I'd appreciate it. Thanks in advance!

flight time is determined by the falling height: the building did not change height.
