A 70kg bicyclist (including the bicycle), initially at rest pedals up a hill. She reaches a speed of 4m/s despite experiencing a 20N drag during her ride. The distance and height of the hill are shown. Neglect any friction impeding her motion and the rotational energy of the wheels. List the energy types at the initial and final time and whether work 75m and loss (due to non-conservative forces) occur as well as the 13m corresponding amounts of energy. reference level initial: Nene o 9=10mls2 Vsand =343 m J work?
