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?

Your refrigerator has a mass of 104.5 kg, including the food in it. It is standing in the middle of your kitchen, and you need to move it. The coefficients of static and kinetic friction between the fridge and the tile floor are 0.44 and 0.35, respectively. What is the magnitude of the force of friction acting on the fridge, if you push against it horizontally with a force of each magnitude? ( in number format with 4 decimal places)...

1. You have one last large 50 kg crate to move from your apt to your car and your inconsiderate roommate took the cart with him. So in order to move the crate, you tie a string to it and pull at an angle of 30° above the horizontal such that you move the crate along at a relatively constant speed. The coefficient of kinetic friction between the floor and the crate is 0.2 and the coefficient of static friction...
