(b) What coefficient of static friction between the 130-N block and the table ensures equilibrium? (Enter the minimum acceptable coefficient of friction.) (c) If the coefficient of kinetic friction between the 130-N block and the table is 0.212, what hanging weight should replace the 55.0-N weight to allow the system to mc constant speed once it is set in motion?
