A loaded sledge slides across a flat, snow-covered field. The sledge initially has 160 J of energy in its kinetic energy store.
As the sledge moves 5.0 m, a frictional force of 22 N acts against its motion. No other force does work on the sledge.
Calculate the energy in the kinetic energy store of the sledge after it has moved 5.0 m.
Explain why the temperature of the sledge's runners increases as the sledge slides.
