A skier starts from rest at the top of a frictionless incline of height 20 meters. At the bottom of the incline, the skier encounters a horizontal surface where the coefficient of kinetic friction Between skis and snow is 0.193. Neglect air resistance.  Find the horizontal distance the skier travels before coming to rest if the incline also has a coefficient of kinetic friction equal to 0.193. Assume that the angle is 20 degrees.

Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.
