A 25 kg chair initially at rest on a horizontal floor requires 360 N horizontal force to set it in motion. Once the chair is in motion, a 316 N horizontal force keeps it moving at a constant velocity.
a) Find the coefficient of static friction between the chair and the floor.
b) Find the the coefficient of kinetic friction between the chair and the floor.
