They both land at the same time
Explanation:
Both balls start with nil velocity in the vertical direction. They both have the same height to fall and both accelerate in the vertical direction at g, 9.81m/s/s. Hence they both spend the same time falling. The vertical velocity is unaffected by the horizontal velocity.
