In the figure below, m m1 = 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. mq (a) If the system is released from rest, what will its acceleration be? (Enter the magnitude of the acceleration.) m/s (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/s
