In the figure below, m1 = 9.0 kg and m2 = 4.0 kg. The coefficient of static friction between m1 and the horizontal surface is 0.60 while the coefficient of kinetic friction is 0.30.

(a) If the system is released from rest, what will its acceleration be?

Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. m/s2

(b) If the system is set in motion with m2 moving downward, what will be the acceleration of the system?
m/s2
