Can anyone please help me with the following problems? I’ve tried but I just don’t get the answers.

Explanation:

2) Draw a horizontal line below the squiggle and call it your reference origin.

Highest potential energy is farthest above the origin.

I would suggest for highest to lowest

GACE(D = F)B

3) I have no way of knowing how to compare kinetic and potential energies because we are given no reference levels for either.

IF we ASSUME it is a typo and they want highest to lowest KINETIC energies, then the values will be the reverse of #2 because, in the lack of friction, Kinetic and Potential energies will always be swapping keeping the total mechanical energy constant.

B(D = F)ECAG
