When Comparing The Force That Is Required To Climb A Mountain By Walking Up A Trail That Slopes Gently Upward To The Top,versus Getting There By Scaling A Sheer Vertical Cliff Face,which Of The Following Is A True Statement?
(A) you use more force for a given distance of movement on the walk than on the climb.
(B) walking up the trail forces you to cover a greater distance, but the amount of force needed to cover a given distance will be less.
(C) scaling the vertical cliff, while dangerous,uses less force than 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
