In the figure below, m1 = 9.5 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.
Without the "figure below", or a better description of the problem, I cannot help you. Sorry.
By the way, you omitted whatever the question is.
