Fred pushes a 55 kg refrigerator with a force P = 100 N inclined at 30° from the horizontal at 1.60 m from the floor as shown in the diagram. The coefficient of static friction between the floor and the refrigerator is 0.40. 1. Which among the choices shows the limiting value of the frictional force between the refrigerator and the floor? A) 90.9 N B) 195.8 N C) 108.8 N D) 490 N 2. Is the refrigerator not moving, moving, or on the verge of moving? Prove this through calculations. 3) Write the correct moment equilibrium equation about A for the refrigerator. (Just use P, don't use P =100)
