Three rectangular boxes are stacked on top of each other. All the boxes have the same mass of 1.2 kg. The kinetic coefficients of friction between the boxes are all 0.6 and the static coefficient of friction is 0.7. There is no friction between the bottom box and the floor. A rope is attached to the lowest box and pulls on the lowest box with a force of 5.0 N. Is the friction between the boxes static or kinetic?
