Missing force Afree-body diagram is shown below for a box of mass m that is moving horizontally across a flat surface, but one force is missing from the diagram. Determine the magnitude ofthe missing force for each ofthe three situations below. FN = 0. 8mg @ Partla) 0 Homework I Unanswered I Due Oct3rd, 12:15 PM Use mg = 20.0 N.
