A crate of mass 40 kg sits on a level surface that has friction. An applied force of 250 N at some angle below the horizontal acts on the crate so that it moves horizontally at a constant speed. The force and its x and y components are shown in the diagram. The normal force acting on the crate will be most nearly... A. 640 N
B. 540 N
C. 390 N
