Here is a simple experiment that you can do at home to determine the Kinetic Coefficient of Friction for a coin.

Some assumptions include that the coin experiences uniform acceleration while sliding along a ramp, and that the ramp has the same coefficient of friction throughout.

This video explores the fundamental force equations for an object that is sliding along an inclined plane.

See the thumbnail for details related to the equations of motion for the coin.
