Answer:

0.163934

Explanation:

Kinetic friction can be calculated by coefficient of kinetic friction * normal force. In this question the Mg is = to normal force (12.2 N). Therefore using sum of forces equations we get 2N = coefficient of kinetic friction * 12.2N. divide 2 by 12.2 to get the coefficient.
