Question

Quizplus · Accepted Answer

In the presence of air resistance, the ball experiences a drag force that opposes its motion. This causes the ball to lose some of its initial velocity as it moves upward, and to gain velocity as it moves downward. Therefore, when it is caught on its way down, its speed will be less than its initial speed.
