If one object is sliding on the surface  (i.e. it is in motion relative to the other one ) then there is a force of kinetic friction between the two objects. the direction of this force opposes the sliding motion and its magnitude can be calculated by:

fk=μkN

where:

N= normal force between the two objects and

μk=the coefficient of kinetic friction for the two surfaces.

from our description above we can be able to derive the equation

                               20=μk X 10

 and thus the coefficient of the kinetic friction for the two surfaces will be  2
