PE = m g h
290 * 103 = 70 * 9.8 * h
h = 422.74 m
her altitude = 1250 - 422.74
= 827.26 m

Thermal question
A 60-kg hiker plans to climb Mt Kosciuszko (2228 m) starting from Thredbo (1365m). Assume that she is 25% efficient at converting chemical energy from food into mechanical work, and that essentially all the work goes into the vertical climb. (a) (3 marks) With reference to the data above, how many servings of Nutrigrain should she eat to provide enough energy for the climb? (b) (6 marks) Climbing a mountain warms you up, and makes you sweat one...
