The force of friction is 0.8 N.
Friction is the force that prevents motion when the surface of one object comes into contact with the surface of another.
μ is the coefficient of friction between the surfaces which are in the contact.
Fn is the normal force acting on the object due to its mass.
Mass of the object = m = 8.0 kg
coefficient of kinetic friction between an object and the surface upon which it is sliding = 0.10
Frictional force = F = 8.0 * 0.10
F = 0.8 N
