A refrigerator is being pushed up a slight inclined plane of 10 degrees, as is shown in the figure below. The weight of the refrigerator is 550 N. The coefficient of static friction for the base of the refrigerator on the inclined plane is 0.3. The coefficient of kinetic friction for the base of the refrigerator on the inclined plane is 0.1. The refrigerator is 2m high and 1m wide. What is the max height above the inclined plane that a force parallel to the inclined plane could be applied to the refrigerator that would allow the fridge to start sliding up the inclined plane, rather than causing it to tip over.
