Use the following information and illustration for questions 24-26. The path of a sledder is shown below; upon descending the hill, the sledder ultimately glides up a
ramp to a final resting position (at D). Frictional forces can be assumed to be negligible. (Given: m =
30 kg; Height at A = 6 m, Speed at A = 14 m/s.) Fill in your answers on your scantron and only for the
questions asked on 7-9 (you do not need to fill in the entire chart).

h = 4 m at B
24. Kinetic Energy at Point B. Round to the nearest whole number.
25. Potential energy at Point B. Round to the nearest whole number.
26. Velocity at point B. Round to the tenth place (1 decimal place)

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000

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
