Q11-MTE

11. A 0.225-kg box initially rests on a wooden table. The box is attached to a massless string that passes over a small frictionless pulley and is attached to a mass hanger. a. What is the maximum acceleration of this system? b. What is the minimum acceleration of this system? c. When a 0.150-kg mass hangs from the other end of the string, the system moves with constant speed. What is the coefficient of kinetic friction between the table and the box? d. An additional 100-g is added to the end of the string. What is the acceleration of the system?
