A 83kg teacher (including the mass of his gear) hikes up a mountain! During his hike he experiences a 5N drag (and negligible friction impeding her motion). The distance of the path and the height of the mountain are shown. List the energy types at the initial and final time and whether work and loss (due to non- conservative forces) occur as well as the corresponding amounts of energy.
