Can you help? I think the answer is D, but I'm not sure.?

Question

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, whicle dangerous, uses less fore than going the "gentler"way around.

d) The distance covered is the same either way, but scaing the cliff is harder because you ar working against gravity.

Answer 1

B

Answer 2

Answer a) is incorrect because walking up a slope is opposing the force of gravity at an angle so a lesser force is required.

Answer b) is correct.

Answer c) is incorrect because scaling a vertical cliff is opposing the force of gravity directly so a greater force is required.

Answer d) is incorrect because walking up a slope requires more distance to travel than scaling up a vertical cliff.

Answer 3

the answer is B

it isnt D because the distance would be much greater on the trail
