Bowling ball and table!!!

Can anyone please help me figure this one out;

A bowling ball of mass 7.5kg travelling at 10m/s rolls off a horizontal table 1.0 m high. Calculate the velocity of the ball as it reaches the floor, ignoring air resistance and having an acceleration due to gravity of 9.8m/s.

They gave you the horizontal component of velocity. They want you to find the vertical component and then combine the 2 like Pythagoras would to yield the answer for the magnitude of the |velocity| vector. Now they may also want you to give the direction. (That would be tan-1 of the ratio of the 2.)
