A large mass M = 9.00 kg hangs from a massless rope that is connected to a box, m = 5.00 kg. The rope passes over a massless pulley and does not stretch. Due to the hanging mass, the box is accelerated along the surface to the left. a) Draw free-body diagrams for the mass, M, and the box, m. Indicate xy-coordinate directions for each object. Indicate the direction of positive acceleration.  b) If the acceleration of the box is 5.50 m/s2 determine the coefficient of kinetic friction µk between the box and the table surface.
