when comparing the force that is required to climb a mountain walking up a trail that slopes gently upward to the top verses getting there by scaling a sheer vertical face, which of the following is true?
(a) you use more force for a giving movement on the walk than on the climb, walking up the trail forces you to cover a greater distance,
(b)but the amount of force needed to cover a given distance will be loss,(c)scaling the vertical cliff while dangerous uses less force that going the gentler way around,
(d) the distance covered is the same either way but scaling the cliff is harder because you are working against gravity
the answer is B
