An anvil has a volume of 0.032m^3 and a density of 7965 kg/m^3. if it is dropped into a swimming pool 1.43 m deep, how much energy is lost during the fall and while striking the ground? answer in joules. hint: as the anvil falls, an equal volume of water is displaced. this water must rise to the surface of the pool, raising the level of the water very slightly.
