(D) is incorrect

... but mass multiplied by G^2 multiplied by height.
No, the formula for gravitational potential energy is $GPE = mgh$, where $m$ is the mass of the object, $g$ is the acceleration of gravity near the Earth's surface, and $h$ is height above a reference position, which would be the bottom of the hill in this case.

Using that formula my answer will be A. 0.466J, I think that’s right. If you wouldn’t mind, can you help me solve another one similar to this but I’m sure it has a different equation. Thank you for the help btw

(A) is correct.

Start a new thread for a new problem. That way, if I can't get to it, someone else may be able to offer help.
