Question 1 (1 point) A ferry is being pushed with a force of 40.0 N [W] by its engines. It enters a strong current from the north, which exerts a force of 30.0 N on the ferry. What is the net force acting on the ferry 50.0 N [W 36.9% E] 50.0 N [W 53.1" E] 70.0 N [W 36.9% E] 70.0 N [W 53.10 E] Question 2 (1 point) A lumberjack pulls with a force of 100 N [N] on a rope attached to a tall tree. A second lumberjack pulls with a force of 80 N [E] on a rope attached to the same tree. In what direction is the net force acting on the tree? O northeast, but closer to east due north directly northeast O northeast, but closer to north Question 3 (1 point) Lars puts on a pair of wooden skis, and stands erect on a level snowfield. The coefficient of static friction between his skis and the snow is 0.22. If he has a mass of 75 ke. what is the minimum force required to start him moving across the snow? 17 N O 98 N 740 N 160 N
