You are helping your friend move a new refrigerator into his kitchen. You apply a horizontal force of 263 N in the negative x direction to try and move the 54 kg refrigerator. The coefficient of static friction is 0.67.
A) How much static frictional force does the floor exert on the refrigerator? Give both magnitude (in N) and direction.
B) What maximum force (in N) do you need to apply before the refrigerator starts to move?

A large refrigerator (mass 95kg) sits at rest inside a house. The homeowner wants to move the refrigerator across the room, so she begins to push it. The coefficient of static friction between the refrigerator and the floor is 0.6, and the coefficient of kinetic friction is 0.5. The homeowner applies a horizontal force of 400N on the refrigerator. What is the magnitude of the force of friction acting on the refrigerator as she applies that force?
