Answer:
<em>The first option best compares both ramps: "It takes less effort to wheel boxes up the 5 m ramp, but the distance is greater"</em>
Explanation:
Power and Work
If an object is being lifted by a vertical distance y, the work done by the agent is the same regardless of the path taken to reach that heigh. But the power could be different since it depends on the time needed to do the work.
The question talks about 'effort' which we'll assume to be the power, since, as noted above, the work is the same by using any of the ramps. The 5 m ramp makes the job easier because the worker has to push less. It's due to the fact that the component of the weight depends on the sine of the angle formed by the ramp with the floor. The larger ramp makes a shorter angle, thus requiring less effort, through a longer distance.
Thus, the first option best compares both ramps:
<em>It takes less effort to wheel boxes up the 5 m ramp, but the distance is greater</em>
