Solve Kinematic Problem: Ball Falls 1.52m from Table

[assaftolko]

A ball moves to the edge of a table which is 1.2 m above ground. The ball falls off and hits the ground 1.52 m horizontly from the edge of the table.

(a) How much time does it take the ball to hit the ground?
(b) What's the ball initial velocity?

Am I to understand that the initial velocity is only horizontly (Vo,x)? Because if it's not I don't know its size, the angle it creates with the horizon and the time factor... 3 variables with 2 equations...

Yes, assume the initial velocity is horizontal.
