1) a concrete block of mass M=15000kg is at rest on a dock.The coefficient of static friction between block and dock is us=0.90. A cable is used to lift a mooring anchor from the harbour as shown in figure... a) what is the maxium mass m of the anchor that can be held in position shown b) if m has its maximum value,what are the tensions T1 and T2
