A 20.0-N block rests on a horizontal surface. The coefficients of static and kinetic friction between the surface and the block are 0.860 and 0.590, respectively. A horizontal string is attached to the block and a constant tension is maintained in the string. What is the force of friction acting on the block if the tension is 21.20 N?
