Ahill has three paths up and sides to a flat summit area that three path lanks are different but the vertical height from the bottom of the mountain to the top is the same
a) which path would be easiest for a car to claim
b) not including the energy used to overcome the internal friction of the car which path requires the most energy for a car to climb?

i’m just confused on the concept of work. how come work is not affected when there is the same height
