A 325 N force is pulling on an 85.0 kg refrigerator as it slides across a horizontal floor. The force acts at an upward angle of 25.0° above the horizontal. The coefficient of kinetic friction between the refrigerator and the floor is 0.150, and the refrigerator moves a distance of 5.50 m. Find (a) the work done by the pulling force, (b) the work done by the force of kinetic friction, (c) the net amount of work done on the refrigerator, and (d) if the refrigerator was initially at rest determine the speed of the refrigerator after the 5.50m displacement. (e) Include a force (or free-body) diagram of the situation. [Diagram 2 pts.]
