Unformatted text preview: SOLUTION a. Since the refrigerator does not move, it is in equilibrium, and the magnitude of the static frictional force must be equal to the magnitude of the horizontal pushing force. Thus, the magnitude of the static frictional force is 267 N . The direction of this force must be opposite to that of the pushing force, so the static frictional force is in the + direction x . b. The magnitude of the largest pushing force is given by Equation 4.7 as MAX 2 s s N s = = (0.65)(57 kg)(9.80 m/s ) = 360 N f F m g = ______________________________________________________________________________________ ______...
