A large statue, with a mass of 180 kg, is lifted through a height of 2.33 m onto a display pedestal. It is later lifted from the pedestal back to the ground for cleaning. 

a) Calculate the work done by the applied force on the statue when it is being lifted onto the pedestal.

(b) Calculate the work done by the applied force on the statue when it is lowered down from the display pedestal.

(c) State all of the forces that are doing work on the statue during each motion.
