I NEED AN ANSWER!
A sled going down a hill covered in snow eventually comes to
a stop. Explain why this happens in terms of energy. Use
the terms potential energy, kinetic energy , and friction.
Before sled starts to move it has a potential energy due to the elevation...and then that potential energy converted to kinetic energy due to presence of a velocity...the sled will continue to move if their is no resesive force...but however friction force is presence that cause the sled to stop....
