Two Margaret Atwoods with different masses (m1= 34 kg and m2= 48 kg are connected by a massless string that passes over a massless and frictionless pulley, as shown in the picture below. The both Margarets are moving but the second Margaret (mass m2) moving and accelerating downwards. The coefficient of kinetic friction between the first Margaret (mass m1) and the horizontal surface is 0.20. What is the acceleration of the second Margaret (mass mB) in the y direction (units of m/s^2)? Provide your answer as a positive or negative number ONLY, with 2 decimal places (e.g. 1.25 or -1.25). Do not write the units (e.g. s or m or m/s etc.) in the answer box. Do not use scientific notation.
