A 72-kg water skier is being accelerated by a ski boat on
Chapter 4, Problem 91(choose chapter or problem)
A 72-kg water skier is being accelerated by a ski boat on a flat (glassy) lake. The coefficient of kinetic friction between the skiers skis and the water surface is (Fig. 474). (a) What is the skiers acceleration if the rope pulling the skier behind the boat applies a horizontal tension force of magnitude to the skier (b) What is the skiers horizontal acceleration if the rope pulling the skier exerts a force of on the skier at an upward angle (c) Explain why the skiers acceleration in part (b) is greater than that in part (a)
