Charles · Answer 1

45 kg dog on a 5 foot high rock

Step-by-step explanation:

The equation for potential energy is PE = mgh, which is mass x 9.81 x height

You increase either the height or the mass you will increase the PE. Since the 45 kg was the most and 5 foot was the highest thus it would have the highest PE.
