While moving a 71 kg box across a horizontal floor, you find that it takes a 190 n force to get the box moving (pushing horizontally), but just a 120 n force to keep it moving at constant speed thereafter. what is the coefficient of static friction between box and floor? what is the coefficient of kinetic friction between box and floor?
