Verdah, Hetav and Dhinesh are undertaking an investigation into the motion of wooden blocks in their Physics class. Their aim is to determine the effect that mass has on the horizontal motion of the wooden block across a table. Verdah suggests that they use a launcher to give both blocks the same initial velocity and that they use the same table for each trial.
The blocks are made from the same wood but have different masses. The mass of block A (m1) is twice the mass of block B (m2). The coefficient of friction between the blocks and the table is u.

a. Hetav hypothesises that block A will travel a greater distance across the table before coming to rest. WITHOUT using an equation provide an explanation for Hetav's hypothesis.

b. Dhinesh disagrees with Hetav and states that block B will travel a greater distance before coming to rest. WITHOUT using an equation provide an explanation for Dhinesh's hypothesis.

c. Derive a mathematical expression that the students could use to find the distance block A travels after it leaves the launcher. Upload a copy of your HANDWRITTEN working clearly identifying all equations and constants used in your derivation. Make sure your name is visible next to your working.

d. Using the equation derived in part c to support your answer, justify if Hetav or Dhinesh was correct in their hypothesis.

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
