A 55kg student runs up a flight of stairs in 20s. The distance and height of the stairs are shown. Neglect loss. 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. initial: none work? work loss? no loss V3= 45m final: GPE 10 What was her average power output? rad reference level
