Answer :
If I throw a ball straight ahead and then my friend drop the identic ball to the ground, so both ball will hit ground together. It happens because the only force act to the both balls vertically is only gravity.
In this experiment, the two balls have different horizontal velocities, but that does not affect the vertical motion. Both balls start with zero vertical velocity, and accelerate at the same rate of gravity.
