A driver and his scuba suit have a combined mass of 100 kg. The diver is using a 5.0 kg tool kit to repair a deep-sea panel on the International Deep-Sea
Station. When the tether connecting the diver to the submarine becomes
unattached, the diver, still holding the tool kit, starts to float away at 0.4 m/s.
The diver realizes that the only way he will be able to change his motion and
move back to the deep-sea station is to throw the tool kit. State which
direction should throw his tool kit. Use the law of conservation of momentum
to justify your answer.
(Should he throw it away or towards and WHY?)

so here is the information for current research:

-nrel's geothermal analysts, scientists, and engineers perform a full range of research from developing advanced methods of locating and accessing geothermal resources to exploring innovative technologies to extract and produce clean energy from the heat of the earth

and here is the information for the technology of geothermal energy:

-it's clean and sustainable

-resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma

-almost everywhere, the shallow ground or upper 10 feet of the earth's surface maintains a nearly constant temperature between 50° and 60°f (10° and 16°c)

-geothermal heat pumps can tap into this resource to heat and cool buildings

-a geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building

-in the winter, the heat pump removes heat from the heat exchanger and pumps it into the indoor air delivery system

-in the summer, the process is reversed, and the heat pump moves heat from the indoor air into the heat exchanger

-the heat removed from the indoor air during the summer can also be used to provide a free source of hot water
