Physics Problem. Determine coefficient of static friction and acceleration.

Suppose m1 = 5.2 kg and m2 = 2.8 kg. Assume the pulley is massless and frictionless. A) What coefficient of static friction between the 85.0 N block and the table ensures static equilibrium? B) Suppose the coefficient of kinetic friction between the 85.0 N block and the table is μk = 0.32. Once it is set in motion, what acceleration would the 85.0 N block have?
