Hi,

what is the influence of the horizontal velocity of the ball on the result?

I don't really know what you're trying to ask sorry. But 9.8g uhh is the gravitational force... <_>

I want to simplify the problem and rule out all the information, which are not necessary to solve the problem. My question was: would it make a difference, if the ball would have a horizontal velocity of 10 or 20 m/s or any other value?

The question is over specified (and inconsistently so). You are given both the time of drop and the distance.
What are you told to use as the value for g, 10m/s, 9.8 or 9.81?
To get one of the offered answers you need to ignore the drop distance and use a g of 9.8 or 9.81.

Hmmm... 9.8m/s you mean.
