Mary applies a force of 80 N to push a box with an acceleration of 0.40 m/s². When she increases the pushing force to 86 N, the box's acceleration changes to 0.63 m/s². There is a constant friction force present between the floor and the box. (a) What is the mass of the box in kilograms? 200 x Consider applying Newton's Second Law to each the pushing forces. kg (b) What is the coefficient of kinetic friction between the floor and the box? -0.020 x What is the relation between friction force and normal force? Did you apply Newton's Second Law to motion in the vertical direction?
