in the vertical direction the motion of the two rocks is identical. They accelerate down with acceleration -9.81 m/s^2
The fact that one of them is moving with constant velocity (there is no force in the x direction) is irrelevant to the motion in the vertical direction
Therefore they hit simultaneously.
