A student pushes a box at a constant speed along a rough floor.
The student pushes with a force of 25 N for a distance of 4.0 m.
Which statement describes the energy transferred by the push?
100 J100\ \text{J}100 J to the thermal store of the box and floor
100 J100\ \text{J}100 J to the kinetic store of the box
6.25 J6.25\ \text{J}6.25 J to the thermal store of the box and floor
6.25 J6.25\ \text{J}6.25 J to the kinetic store of the box
