Note that the kite goes down faster than it goes up. So, the correct graph must show a higher inclination or slope at last, as the second chart is showing.
- Why the other options are not correct?
• The first chart shows a constant movement at first, which is not the real situation because when the child lets the string out, the kite won't have the same height.
,
• The third chart doesn't represent the situation because the kite doesn't fall quickly, but it falls at certain intervals.
,
• At last, the fourth graph is similar to the second one but it shows that the kite goes down slower.
Therefore, the correct chart is the second one.
