In the figure below, m, = 11.0 kg and m, = 3.9 kg. The coefficient of static friction between m, and the horizontal surface is 0.60, and the coefficient of kinetic friction is 0.30. m] (a) If the system is released from rest, what will its acceleration be? (Enter the magnitude of the acceleration.) m/s 2 (b) If the system is set in motion with m, moving downward, what will be the acceleration of the system? (Enter the magnitude of the acceleration.) m/s2
