Friction between the box and the inclined plane.
Explanation: As the box slides up, kinetic (and work) energy is dissipated by sliding friction with the plane and converted to thermal energy. (If the box also slides against the truck as it’s loaded, that contact can dissipate energy too. Static friction at Lenore’s hands or feet, when there is no slipping, does not dissipate energy as heat.)
