Physics question involving zero launch angle?

In Denver, children bring their old jack-o-lanterns to the top of a tower and compete for accuracy in hitting a target on the ground. Suppose that the tower is 9.0 m high and that the bull's-eye is a horizontal distance of 3.5 m from the launch point. If a jack-o-lantern is given an initial horizontal speed of 3.3 m/s, what is the direction and magnitude of its velocity just before it lands?
