As shown in the figure, you pull a loaded sled whose mass is 20 kg at constant speed in the x direction with a rope at an angle of θ = 25∘. The coefficient of kinetic friction between the snow and the sled is 0.25 . Consider the sled to the be the system. a) What are the surroundings? b) Draw a free-body diagram. c) What is the magnitude of the tension force in the rope? d) What is the magnitude of the normal force?
