Friction between Jethro and the ground.
Friction between Jethro and the ground.

Friction between the box and the ramp (incline plane).

Answer 1

In this scenario, energy is primarily being lost due to **friction between the box and the ramp (incline plane)**. This friction opposes the motion of the box as Jethro pushes it up the ramp, converting some of the mechanical energy into heat energy, thus leading to energy loss.

So the correct response is:

**Friction between the box and the ramp (incline plane).**
