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)
