A 75kg bicyclist (including the bicycle), initially at rest pedals up a hill. She reaches a speed of 4m/s despite experiencing a 15N 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 and loss (due to non-conservative forces) occur as well as the corresponding amounts of energy. initial: work? loss? final: none work loss GPE & KE 1111 = 0 11325 What is the average thrust she must generate? 153 unit
