In a biomechanics test, a subject performs two lifts of the same box: Lift A raises it 0.50 m0.50\ \text{m} vertically; Lift B raises it 0.25 m0.25\ \text{m}. Both start and end at rest, and losses are negligible. Principle tested: work against gravity. Which prediction is most consistent with the mechanical work done on the box by the subject?
