a box of mass 5 kg lies on a shelf connected with a string to a fictionless pulley with a box of mass 2kg on the other end of the string hanging vertically. the coefficient of static friction between box of 5kg and the shelf is .70. the coefficient of kinetic friction is .40. what is the acceleration of the boxes if the system is released from rest. If the system is set in motion and the box of 2kg is moving downward, what is the acceleration of the system.
