Coefficient of static friction between chair and floor


A 27 kg chair initially at rest on a horizontal floor requires a 376 N horizontal force to set it in motion. Once the chair is in motion, a 345 N horizontal force keeps it moving at a constant velocity. The acceleration of gravity is 9.81 m/s2.

a) What is the coefficient of static friction between the chair and the floor?
