Your brand new 75.0-kg refrigerator falls out of the back of your truck while you are traveling up a 45.0° incline. It slides 55.0 m to the bottom of the hill and is miraculously unharmed. The coefficient of kinetic friction between the refrigerator and the road is µk = 0.45. (a) Calculate the work done on the package by friction. (b) Calculate the work done on the package by gravity. (c) Calculate the work done on the package by the normal force. (d) Calculate the net work done on the package.
