If the boat is disconnected from the spars, determine the minimum number of half turns the rope must make around the boom so that the boat can be safely lowered into the water at constant velocity. The coefficient of kinetic friction between the rope and the boom is s = 0.15. Hint: The problem requires that the normal force between the man s feet and the boat be as small as possible. Express your answer as an integer. n = 3 Correct Part B Previous Answers What is the magnitude of the normal force between the boat and the man?
