    Pulley Systems: HELP!!

    Hey guys so I'm trying to do this last question on the homework but I'm stumped and don't even know where to begin...Can someone please help me out?

    Two masses are connected by a string that passes over a pulley. Mass#1 of 10kg is on a frictional surface with coefficients of static and kinetic friction of 0.8 and 0.5, respectively. (a) find the maximum weight of mass #2 before the system just barely wants to move. (b) Find the weight of mass #2 so that the system moves with a constant velocity.
