A hiker of mass 58 kg climbs up a mountain through a verticaldistance of 950 m. To make the climb, her bodygenerates an extra 4.5 X 10^6 J of energy.
A) How much work does she do in changing her gravitationalpotential energy?
B) What is her efficiency (expressed as a fraction between 0and 1) in doing the work in part (a)?
