Compute all parts of following problem:
Problem: Mary applies a force of 72 N to push a box with an acceleration of 0.44 m/s2. When she increases the pushing force to 80 N, the box's acceleration changes to 0.65 m/s2, there is a constant friction force present between the floor and the box.
Part I: What is the mass of the box?
Part II: What is the coefficient of kinetic friction between the floor and the box?
I need help to determine the coefficient of kinetic friction between the floor and the box.
