 Homework Statement:
 A 71.5kg hiker starts at an elevation of 1300 m and climbs to the top of a peak 2680 m high. What is the minimum work required of the hiker?
 Relevant Equations:

w=(Fcos[theta])d
F=ma
PE=mgh
f=ma=71.5*9.8 = 700.7 I know this is not right because he is also going up against gravity but I don't know what else to use for acceleration. I don't know the angle but I assume it is a 90 degree cliff.
w = (Fcos90)1380 = 0. But zero is not the correct answer.
w = (Fcos90)1380 = 0. But zero is not the correct answer.
