to the roof of a building. Another man uses a ladder
against the wall of the building to reach its roof. Will
they both possess the same amount of potential
energy? Justify your answer.​

Answer 1

Answer:

Both possess the same amount of potential energy.

Explanation:

Potential energy does not depends on the path.

PE = mass x g x height= mgh

In both the cases the height attained is same so the potential energy is also same for both considering the mass being constant.

Answer 2

PE=MASS x G x Height = mgh

in both, the height attain the same so the potential energy is also same for both considering the mass being constant.
