Question

Quizplus · Accepted Answer

Air resistance is a form of friction that opposes the motion of the ball. As the ball is thrown up, it has an initial velocity that helps it overcome the force of air resistance. However, as it reaches the highest point of its trajectory and begins to come down, the force of air resistance begins to slow it down. This means that the time it takes for the ball to come down is longer than the time it took to go up, as it is moving against resistance. Therefore, the correct choice is C) more.

A Ball Is Thrown Vertically into the Air
