Worked Solution

Step 1: The ball has horizontal motion from the throw. Step [2-9]: Gravity pulls the ball vertically downwards at all times. Step [2-9]: The combination of horizontal and downward motion results in a curved (parabolic) path.

Correct answer: A curved path downwards because of gravity pulling it towards the center of the Earth.
