A pulley system is used to raise a shipping container from the dockto a cargo ship. An effort force of magnitude 6.8 x 10*4 N isrequired to lift a load of mass 3.5 x !0*4. the effort force moves54 m while the load is raised 8.7 m.

(a) Calculate the magnitude of the load force
(b) Calculate the IMA, the AMA and the percent efficiency of thepulley system
