A water-skier with a mass of 68 kg is pulled with a constant force of 870 N by a speedboat. A wave launches him in such a way that he is temporarily airborne while still being pulled by the boat, as shown in the image below. Assuming that air resistance can be ignored, what is the vertical acceleration that the water-skier experiences on his return to the water surface? (Recall that g = 9.8 m/s2) O A. -13.6 m/s2
O B.-17.1 m/s?
O C. -22.5 m/s2
O D.-9.8 m/s2

all of the answers are correct.

falsification is manipulating research materials, equipment, or processes or changing or omitting data or results such that the research is not accurately represented in the research record. plagiarism is the appropriation of another person's ideas, processes, results, or words without giving appropriate credit.
