Juanita did more work on the square box
Explanation:
According to the law of conservation of energy, the work done in lifting an object is equal to the increase in gravitational potential energy of the object. This is due to the fact that the work done on the object is converted into potential energy.
The potential energy of an object (GPE) is given by
where
m is the mass of the object
g is the acceleration of gravity
h is the height of the object
In this problem, we have two objects:
- The roud box is lifted and its GPE increases by 50 J --> this means that the work done by Juanita on the box is 50 J
- Thr square box is lifted and its GPE increases by 100 J --> this means that the work done by Juanita on the box is 100 J
Therefore, Juanita did more work on the square box.
