The energy lost operating a low-speed chairlift is the same as the energy lost operating a high-speed lift of equal path length. What happens to the efficiency when you change from a low speed to a high speed chairlift?
We know that high speed chairlifts use more power so that they can go faster.
The Attempt at a Solution
My initial thought was that it would be less efficient because more power is used... but if they stay the same, less of the power will be wasted... making it more efficient??
