Which object had more potential energy when it was lifted to a distance of 10 meters? Show your
calculation. (Remember that gravity = 9.8 m/sec2)

When all of the objects are lifted to the same height, the object that has the most mass also has the most potential energy.If we knew anything about the masses of the objects in this question, then we could be more specific.Calculation:    Potential energy = (mass) x (gravity) x (height above the reference level).
