The dog stole the baby's dirty diaper that Kristan had just changed and was getting ready to throw away. The dog weighs 15kg and the diaper weighs 2kg. The dog runs outside and climbs up the stairs to the playhouse where it accidentally steps a little too far in the slide causing the dog to slide down the slide with the diaper in his mouth. The height of the slide is 1.5m high off the ground. What is the change of potential energy of the dog assuming it started at rest and slid all the way to the ground?
