A person pushes a box 10 m10\,\text{m} with a constant force of 50 N50\,\text{N} on a rough floor. The box starts at rest and ends with 200 J200\,\text{J} of kinetic energy. Assuming all other transferred energy becomes thermal due to friction, how much energy is converted to thermal energy during the push?
