a 10-g fridge magnet is holding a 2.0 piece of paper on the stainless steel fridge door. A normal force of 0.19 N( the horizontal force of the fridge pushing against the attractive, horizontal, magnet accelerated down the fridge with a net acceleration of 0.150 m/s2 when the fridge door is slammed. What is the coefficient of kinetic friction between the steel door and paper?
