B3-WWT36: PULLING A BLOCK ACROSS A ROUGH SURFACE-FORCE RELATIONSHIPS A person pulls a block across a rough horizontal surface at a constant speed by applying a force F at a slight angle as shown. A free-body diagram is drawn for the block. The arrows in the diagram correctly indicate the directions but not necessarily the magnitudes of the various forces on the block. A student makes the following claim about this free-body diagram: "The velocity of the block is constant, so the net force acting on the block must be zero. Thus the normal force F, equals the weight W, and the force of friction f, equals the applied force F." FN fie W What, if anything, is wrong with this statement? If something is wrong, identify it and explain how to correct it. If this statement is correct, explain why.
