4.4: Problems involving Friction 4. A heavy fridge magnet is sliding down a fridge door that has a height of 67.5 cm. The magnet takes 0.92 s to slide, starting from rest, from the top of the door to the bottom. The mass of the magnet is 230 g and the magnetic force holding it to the fridge door is 2.5 N. Using this information, calculate the coefficient of kinetic friction between the magnet and the door. (Hint: start by working out the acceleration.)
