A box of mass 4 kg is resting on a table 1.5 m above the floor. There is also a ledge located 5 m above the floor. First, provide a sketch of this problem. Then, find the gravitational potential energy of the box relative to the floor, and the gravitational potential energy of the box relative to the ledge.
