Answer:

#30 "kJ"#

Explanation:

The force required to overcome the weight of a #33 "kg"# object is

#F = mg#

#= (33 "kg") * (9.8 "m/s"^2)#

#= 323.4 "N"#

The work done to lift such an object up by #94 "m"# is the force exerted multiplied by the distance raised.

#W = F * d#

#= (323.4 "N") * (94 "m")#

#= 30400 "J"#
