2. A 25 kg chair initially at rest on a horizontal floor requires a 165 N hori- zontal force to set it in motion. Once the chair is in motion, a 127 N hor- izontal force keeps it moving at a constant velocity. a. Find the coefficient of static friction between the chair and the floor. b. Find the coefficient of kinetic friction between the chair and the floor
