Answer 1

Energy can be lost in multiple places during this process. Here's a breakdown of where energy loss might occur in the scenario described:

1. Friction between Lenore and the ground: There may be some energy lost due to friction as Lenore pushes against the ground while pushing the box.

2. Friction between the truck and the inclined plane: If the inclined plane and the truck are not perfectly smooth, there could be energy lost due to friction between them.

3. Friction between the box and the inclined plane: This is likely the most significant source of energy loss. As Lenore pushes the box up the incline, friction between the box and the inclined plane will oppose the motion and convert some of the energy into heat.

4. Friction between Lenore’s hands and the box: When Lenore pushes the box, there will also be some friction between her hands and the box, which can lead to minor energy loss.

Given all these points, the most substantial energy loss will likely occur due to friction between the box and the inclined plane. However, all the mentioned sources of friction can contribute to overall energy loss in the system.
