Worked Solution

Step 1: Gravity is a pulling force acting towards the Earth. Step [2-9]: Air resistance is a frictional force that opposes the motion of the ball. Step [2-9]: Since the ball is moving down, air resistance acts upwards.

Correct answer: Gravity pulls it down while air resistance pushes it up.
