A 66 kg water skier is being accelerated by a ski boat on a flat ("glassy") lake. The coefficient of kinetic friction between the skier's skis and the water surface is μk = 0.28.What is the skier's acceleration if the rope pulling the skier behind the boat applies a horizontal tension force of magnitude FT = 240 N to the skier (θ=0∘)? Express your answer to two significant figures and include the appropriate units. a A =????
