If Renata is standing on top of a hill with a kite and the wind is blowing away from her towards the horizon, in which direction will the kite move once she lets go of it?

Respond very briefly.
The kite will move away from Renata, towards the horizon. This is because the wind applies a force on the kite in the direction that the wind is traveling. Since Renata is standing on top of the hill and the wind is blowing away from her, the kite will catch the wind and be pushed in the same direction that the wind is moving, which is towards the horizon. The kite will continue in this direction as long as the wind persists and no other forces alter its course.
