Consider the figure below. (Let w, = 150 N and w, = 60.5 N.) (a) What is the minimum force of friction required to hold the system of the figure above in equilibrium? (b) What coefficient of static friction between the 150-N block and the table ensures equilibrium? (Enter the minimum acceptable coefficient of friction.) (c) If the coefficient of kinetic friction between the 150-N block and the table is 0.202, what hanging weight should replace the 60.5-N weight to allow the system to move at a constant speed once it is set in motion?
