A person lifts a suitcase from the floor and places it on a table. The work done by the person on the suitcase does not depend on

Step-by-step solution

By the work-energy theorem, the net work done on the suitcase is equal to its change in kinetic energy. Since the suitcase starts from rest on the floor and comes to rest on the table, the change in kinetic energy is zero. W_ net = W_ person + W_ gravity = 0 W_ person = -W_ gravity The work done by gravity is -mgh , where mg is the weight of the suitcase and h is the height of the table. W_ person = mgh This shows that the work done by the person on the suitcase depends only on the weight of the suitcase and the ve
