A line drive to the short stop is caught at the same height as it was it was originally hit. Over it's entire flight the work done by gravity and the work done by air resistance, respectively are _____? Answer: Zero; negative

The work done by gravity is zero and the work done by air resistance is negative. This is because the ball ends at the same height it started, meaning the net vertical displacement is zero, so gravity does no net work. Air resistance is a force that always opposes motion, and since the ball has a net displacement, the work it does is negative.
