To determine the height of the balcony, we would typically need the equation that describes the height of the ball at a given time. However, this information seems to be missing from your question.
If you can provide the equation or parameters relevant to the problem, I can help you find the height above the ground of the balcony. Alternatively, if the question is asking for a height that corresponds to a certain condition (like the height at \( t = 0 \)), please specify that as well.
