Question

1. A person pushes on a 57-kg refrigerator with a horizontal force of -267 N; the minus sign indicates that the force points in the -x direction. The coefficient of static friction between the refrigerator and the floor is 0.65. (a) Draw a free body diagram of the system. Show all the forces involved in system. (b) If the refrigerator does not move, what are the magnitude and direction of the static frictional force that the floor exerts on the refrigerator? (c) Since refrigerator was not moving, the person wanted to increase the force applied on the refrigerator. What is the magnitude of the largest pushing force that can be applied to the refrigerator before it just begins to move?
