In the (Figure 1) the coefficient of static friction between mass mA and the table is 0.42, whereas the coefficient of kinetic friction is 0.17. Ignore masses of the cord and the (frictionless) pulley.
What minimum value of mA will keep the system from starting to move?
What value of mA will keep the system moving at constant speed?
