According to the Can Manufacturers Institute, the energy used to make an aluminum can from recycled aluminum is 5% of the energy
used to make an aluminum can from virgin ore. In a typical year, 1.7 billion pounds of aluminum cans are recycled.

To solve this problem we will apply the work theorem which is expressed as the force applied to displace a body. Considering that body strength is equivalent to weight, we will make the following considerations
Work done to upward the object
Horizontal Force applied while carrying 10m,
Height descended in setting the child down
For full time, assuming that the total value of work is always expressed in terms of its symbol, it would be zero, since at first it performs the same work that is later complemented in a negative way.
