Answer:

120 km/h

Explanation:

This is a case of a parabolic motion. For this kind of motion the horizontal component of the velocity does not change in the complete trajectory. That is:

v_x=constant

Then, the velocity of the ball at the moment in which the catcher caught the ball is:

v=120\frac{km}{h}

the velocity of the ball is 120 km/h.
