Mary applies a force of 78 N to push a box with an acceleration of 0.40 m/s?. When she increases the pushing force to 90 N, the box's acceleration changes between the floor and the box. (a) What is the mass of the box in kilograms? kg (b) What is the coefficient of kinetic friction between the floor and the box?
