If Kofi is standing on a hill and drops a ball, what will happen to the ball's movement as observed by Meiling, who is standing at the bottom of the hill? Respond very briefly.
When Kofi drops the ball, gravity will cause it to accelerate towards the ground. As the hill slopes downward, the ball will initially move perpendicular to the ground at Kofi's feet. Then, the shape of the hill and gravity will combine to make the ball roll down the slope. Since Meiling is standing at the bottom of the hill, she will observe the ball rolling towards her, decreasing in altitude as it approaches. If there is no obstacle in the ball's path, it will continue rolling down the hill until it either reaches Meiling, comes to a stop due to friction or an obstruction, or continues past Meiling if it has enough momentum.
