Energy is lost where there is sliding (kinetic) friction:
- Friction between the box and the inclined plane (definitely) — converts mechanical energy to heat.
- Friction between Lenore’s hands and the box (if her hands slip on the box while pushing) — also converts energy to heat.
Friction between Lenore and the ground and between the truck and the plane are static contacts here, so they do no dissipative work.
