15 m/s

Explanation:

Ignore air resistance. According to the law of energy conservation, the total potential kinetic energy of the object remains the same if there's no energy loss. Since the catcher catches the ball at the same height that it was hit, the potential energy is the same. Therefore the ball kinetic energy should remain the same, and so does its velocity.
