A 29 kg chair initially at rest on a horizontal floor requires a 373 N horizontal force to set it in motion. Once the chair is in motion, a
342 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?
b) What is the coefficiend of kinetic frictoin between the chair and the floor?
