A 25kg chair initially at rest on a horizontal floor requires a 165 n horizontal force to set it in motion. Once the chair is in motion , a 1227 n horizntal 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 fllor
