A cable attached to a block of mass 11 kg pulls the block along a horizontal floor at a constant velocity. If the tension in the cable is 5.3 N, what is the coefficient of kinetic friction between the block and the floor?
Answered by drwls

Since there is no acceleration, the rope tension (5.3 N) equals the friction force, which is M g Uk

Solve for Uk, the kinetic friction coefficient
